Plymouth Grand Voyager Repair Questions and Answers

Answer: Open the radiator cap that is located in front of the radiator - slightly hidden. Your engine may not be equipped with a vent plug.

Question: 1991 Plymouth Voyager Van 3.0 mileage: 70,000. AT 60 mph or above 3 speed auto transmission seems to shift in and out of gear. Tachometer will go up and down when this happens. Garage put in rebuilt torque converter and it did not fix it. Then they put in a valve switch and then they rebuilt transmission. All this and it still is not fixed. Then they put on an engine modulator and that did not fix it either.

Answer: Your problem is most likely caused by a faulty transmission control module.

Question:  1992 Plymouth Voyager mileage: 100,000.  My speedometer decides at times to not work at all- when this occurs, the odometer does not turn either.  AutoZone found speedometer cable for me but I don't think that my 1992 even has a cable for this- Haynes repair manual does not help much- can’t find it - and there isn't any good drawings for showing where it is.  How can I tell if it is a cable or a speed sensor or something else since it affects the odometer also?   Tired of guessing how fast I'm going which is usually slower than anyone on the road to be safe than sorry and get a ticket.

Answer:  You are correct, your van does not have a speedometer cable; it has a vehicle speed sensor generator that is located in the transmission.  The vehicle speed sensor generates a signal for the speedometer.

Question:  1994 Plymouth Grand Voyager  mileage: 64,000.  Guys, I need some help.  I have a noticeable shake in the front end that occurs at about 60 MPH - but only if accelerating.   The faster the acceleration, the more noticeable the shake!  Speeds above and below 60 MPH, no problems.  I have replaced the front tires, struts and mounts, had new tires examined and rebalanced, and a front-end alignment.  What should I try next?  HELP!  Thanks Vic

Answer:  From what you have described, it appears the CV joints are starting to fail.  You will need to replace both axle shafts.

Question:  1992 Plymouth voyager  mileage: 110K.  Help...after replacing our van's timing chain and radiator, our mechanic said the tapping noise I am hearing is coming from the valves and I need a valve job (approx. $1200).  I wanted to make it one more year with this vehicle.  Here's my questions” What will happen if I do nothing and ignore the tapping and drive it till summer when I can look for a new vehicle?  Will the engine fail or lock up?  Would it be okay to take it on a couple 300-mile trips?  Any advice on how to decide when to call it quits and go ahead and buy another vehicle?   Thanks--lots of good info here.

Answer:   You may or may not be able to drive you car on a 300-mile trip.  It depends on what is causing the tapping.  There are a number of possibilities that can cause the noise you described.   Two things come to mind.  The noise could be caused by a busted rocker shaft stand on the cylinder head or a lack of oil to the valve train due to a plugged oil passage.

Question:  1996 Plymouth Voyager  mileage: 46,976.   To Whom it may concern, my car air-condition has a foul smell.  What could cause the car air conditioner to smell?  Please list the possible causes.  Thank you.

 Answer:  The nature of an air-conditioner is that it generates condensation “water” as it cools the air passing through it.  The dust in the air sticks to the water and then when the car is shut off, the water and dust stagnates.  Consequentially, when the car is started the next day and the blower is turned on, you get a musty air smell.   The older the car, the more dirt build up and the stronger the smell.

Question:  1992 Plymouth Voyager  mileage: 90,000.  Brakes Not Working - parked my 1992 Voyager Minivan one night and brakes seemed to be working fine.  Next morning brake pedal goes to the floor.  Checked master cylinder and both reservoirs are empty.  See no brake fluid leaks on ground.  Have replaced both rear wheel cylinders in last 9 months, one about 3 weeks ago.  Have replaced front disc rotors and pads about 3 weeks ago as well.   Brakes have been fine since then.  Do I have a bad master cylinder or could the problem be something else?

Answer:  It is possible that you have a bad master cylinder but you should inspect all brake hoses and wheel cylinders as well.  Losing all the brake fluid in a short period of time indicates that you definitely have a leak somewhere. It should show up during the check.

Question:  1990 Plymouth Grand Voyager  mileage: 97,000.  Bob and Ken, Great web site.  First time caller.   Quick question.  A few thousand miles back 75 or 80K the maintenance required light on the dashboard illuminated.  My local mechanic said that Plymouth set those to go off based upon mileage on this particular vehicle.   He reset the light.  Guess what?  It comes back on again recently.  Stupid me did not ask for the reset steps.  What are the procedures to reset that light?  I hate to go buy a $50 manual for a van I plan to sell in a couple of months.  Or, worse yet, pay a Plymouth dealer $200 to put the light out.  BY the way, the van does not have any problems at all.  Gas mileage is still in the upper 20s in the city and in the mid 30s on the highway.  Oh yea the transmission was changed out (standard for these vans) at 88K.  Thanks for the tip.  Pat

Answer:  The check engine light can be extinguished by disconnecting the negative battery cable for approximately five minutes.  However, the “check engine” light will “light” when there is a malfunction in the engine management system.  The fault code is then stored in the computer.  The computer must be scanned to retrieve these stored faults to pinpoint the malfunctioning component.  Because the check engine light indicates something is wrong, a trip to you neighborhood automobile service center sooner rather than later is recommended.

Question:  1995 Plymouth Voyager  mileage: 65,000.  I've been working on this van for about 4 days now and can't find any cause for this problem.  If you put it in gear (drive) and accelerate, it will start to stall.   It has new fuel pump, fuel filter, Hall effect switch, ignition wires, plugs, cap & rotor.  Scanned engine for codes and nothing.  Thought I had it fixed but the customer takes the vehicle, gets 1.5 miles and it stalls.  Same if I drive it.   Also when it stalls it will start right back up.  I’m exhausted with this van.  I've been through all-different types of diagnoses, had 4 other techs give me advice and help me figure out what is going on.  Please if you have any ideas, heard of this before, please let me know.  Thank you

Answer:  Check the alternator, it may be putting out AC voltage spikes.   If it is, you probably know already that computers hate alternating current (AC) voltage.  In addition, check the catalytic converter to be sure it is not plugged or has a loose core inside.

Question:  1997 Plymouth Grand Voyager  mileage: 300,000.  All the gauges on the dash board quit no rpm, gas, speed, temp it’s been at the repair shop for a week they replaced the body module and the transmission module they can’t seem to find an answer.  Hope you can.  Thanks Ossie

Answer:  Check for 12-volt power to the control modules and make sure they are properly grounded.  If this checks out okay, the dash cluster is likely your problem.

Question:  1989 Plymouth Voyager  mileage: 63,094.   I just had my car fixed because my catalytic converters clogged.  They told me I needed to find out why they were clogging and they ran it on the diagnostic machine.  They called me a half hour later and said everything was fine.   Could this happen from just normal wear?   In addition, I am now hearing this rubbing noise on the front driver side.  Also a lot of rattling.  Someone said my shocks were shot.  Could this be?   Help...my dad pass away and he was my mechanic!

Answer:    Catalytic converters plug usually because of a rich fuel mixture.  Have exhaust gases analysis to determine the correct mixture.  As for your noises, without actually “seeing” your car and driving it, it is impossible for us to diagnose your problem.  Talk with friends and neighbors to locate a professional auto mechanic you can trust.

Question:  1992 Plymouth Voyager  mileage: 164,000.  Hey guys, need your help. I have been stiffed for $500.00 bucks.  The engine has been running hot; temperature gauge on hot, blowing cool air.  First it was "running low on oil; tightened timing belt.  Week later same problem: then my so-called mechanic installed a thermostat.  Couple of days later; same problem: this time "needed" a new radiator cause it was leaking antifreeze.  Two days later same problem.  This time they want to stiff me for 350.00 for a "head gasket”, Can't anyone, tell me what is wrong with it?  Need a second opinion.  HELP!

Answer:   If your car is losing coolant, which causes it to run hot, it must be determined where the coolant is going.   It may be an external leak (hoses, water pump, etc.) or an internal leak (head gaskets, cracked head).  Once determining the cause, you can proceed with the cure.
