Rear doors wont open!

Well this is peachy. Both of my passenger backdoors on my 98 Cavalier wont open now. The doors are not electric. Just your plain jane door locks.

Anyone know what would cause this? The passenger side backdoor went first about a 1.5 yrs ago. Just left it cause of money issues. Now the driver side backdoor goes.

What makes no sense to me is that the the locks are locking/unlocking.

1. We live in Minnesota and had a sudden cold spell but also had many back in October. :Roll:

2. Sprayed the hindges over the summer for the added smooth shut.

Does anyone know how to fix this without going to a repair shop? If hubby has to take out inside door panel. How do you do this? He thinks he knows about cars but dosent. Lol

Thank you in advance for any advice and help. :D

Unfurtunately it souds like your door latches are stuck you may be able to get them open by locking then unlocking them pushing pretty hard on the lock lever in unlock direction and trying to open door simultaniously. From inside handle and outside handle. You have to get the door open to remove the screws in the bottom of door panel to remove it. Warning once you get doors open they probably wont shut again, need new latches available from dealer only. "Just fixed one a week ago same problem" Hope helpful. Good Luck!

You need to spray the door loscks with wd 40. The door panels are held on by push conectors. Take and gently pull on one side of the panel a little to see if they will pop out. Be careful not to bend the door panel made out of something like cardboard the can be helped with a screwdriver or a door panel removel tool, there should be two screws one by the inside door handle and one by the armrest. These are usually covered with a small plastic insert. After the door panels are off then spray the door locking mechanism good. Keep working the door try to open and close them if one has been stuck for over a year and a half then it will be hard to get free. If you want to try before removing the door panel, is spray wd 40 on the locking mechanism, with the window down spray wd 40 into and on the door latches, let the wd 40 penertrate for a day then spray them again. Let the wd 40 penetrate some more. Then try opening the doors, sometimes it takes a while, once you are able to get thwe doors open the spray them good, while opening and closing the doors.

I have a 1982 k-10 4x4 longbed pickup and I keep blowing fuses to the cab and cargo light (its the same fuse for both lights). Ive tried a 10 15 and 20 amp fuse and all blow within a few opens of the cab door.

What can I check next?

Frist you need to put back the correct size fuse, not good idea to keep uping the fuse you could burn up some wiring or cause much more damage then just your problem your having. Second you need to look at your door switchs see if there broke or the wire is cut, if not then trace the wire back from door switch to fuse there should be a cut or burnt wire there some where, use a meter and check for continuity.

Ok, ill check the wire paths with a meter. I know its not a good idea about putting in the different amperage fuses but the label for the correct amperage was worn off of the fuse box and I couldnt see what was suppose to go in there exactly.

Thanks!

IF YOU ARE NOT FAMILIAR WITH HOW TO TAKE OFF THE DOOR PANEL----YOU TUBE VIDEOS OFTEN HELP."HOW TO REMOVE DOOR PANEL ON A 1999 CHEVY TRUCK". OR SOMETHING SIMILAR

THE BAD THING IS--THE DOOR IS SHUT, THIS WILL MAKE IT DIFFICULT TO REMOVE THE PANEL WITHOUT MAYBE DAMAGING IT. GETTING TO THE FASTENERS MAY PROVE TO BE A CHALLENGE!

A SMALL TIME BODY SHOP MIGHT DO THIS RATHER QUICKLY AND INEXPENSIVELY----THEY WILL KNOW WHAT NEEDS TO BE DONE, ONCE INSIDE

HOWEVER. SHOULD YOU WANT TO TRY A LAST DITCH EFFORT BEFORE TAKING IT SOMEWHERE.

. TRY THIS

OTHER THAN TAKING THE DOOR PANEL OFF INSIDE AND ACTUATING THE MECHANISM BY HAND. THEN REPAIRING WHATEVER IS WRONG INSIDE

I'VE FOUND THIS TO WORK ON STUCK DOORS

TRY TO THE BEST OF YOUR ABILITY, "UNLOCK THE DOOR" (AS IF IT WOULD OPEN).I MEAN MAKE SURE THE LOCK MECHANISM IS IN THE OFF POSITION (INSIDE) YOU MIGHT EVEN DO IT WITH THE KEY FROM THE OUTSIDE. JUST MAKE SURE IT'S UNLOCKED, TO THE BEST OF YOUR KNOWLEDGE!

HAVE SOMEONE HOLD THE OUTSIDE HANDLE OPENEVEN ROLL THE WINDOW DOWN AND HAVE THEM HOLD THE HANDLE INSIDE (OPEN)---YOUR 2ND TRY

LAY SOMETHING LIKE A SMALL PIECE OF PLYWOOD ON THE DOOR PANEL--EVEN A TOWEL FOLDED UP TO SORTA CUSHION THE PLYWOOD, FLAT AS YOU CAN GET IT, AS CLOSE TO THE REAR OF THE DOOR AS POSSIBLE. THIS WILL SPREAD OUT THE "LOAD", MAYBE PREVENT DAMAGE TO THE DOOR PANEL (LIKE BUSTED PLASTIC)

LAY DOWN IN THE SEAT AND GIVE THE PLYWOOD A GOOD SWIFT MULE KICK!

HOPEFULLY IT WILL POP OPEN, AND YOU DON'T NAIL YOUR BUDDY HOLDING THE HANDLE ON THE OUTSIDE!

AFTER SEVERAL ATTEMPTS. SORTA KNOW WHEN TO QUIT. IT MAY NOT HAPPEN

CONTINUING TO KICK MAY DAMAGE SOMETHING. INCLUDING YOU!

I'VE DONE THIS ON DIFFERENT CARS FOR FRIENDS AND FAMILY, EVEN IN THE AUTO SALVAGE YARD WHEN A DOOR NEEDED TO BE OPENED

SHOULD IT COME OPEN DURING YOUR KICKSINSPECT THE SITUATION---MAYBE A CHUNK OF WOOD--OR A TOY GOT SLAMMED IN THERE. THUS WEDGING IT TIGHT. COULD BE THAT YOU NEED TO SPRAY SOME LUBRICANT IN THE MECHANISM IN THE JAMBJUST DO THIS PRIOR TO CLOSING IT BACK!

I ALSO LOOKED IN YOU TUBE FOR YOUR EXACT SITUATION--YOU MAY FIND SOMETHING SIMILAR FOR OTHER CARS, IF YOU ALTER SEARCH WORDING

LET US KNOW HOW IT GOES

(NEVER HAD THAT PROBLEM WITH MINE)

I bought a truck yesterday and everything is great with the car, except the keys will start the car and open the trunk but won't open the car doors. Anybody have any ideas or where I can go to get help with this.

It sounds a lot like somebody has changed the locks in the doors. If the same key starts car and opens trunk but won't open doors I would say the door locks have been changed, you will have to have another key made for them by a locksmith. If it takes one key for ignition and another for the trunk then the same key should do the doors that does the ignition, in this case it's possible that the ignition has been changed out, leaving you in the same place. Having a key made for the door locks. If you are using a keyless fob then you really need to see a chevy dealer to find out what is going on. Either way it's a real bummer! :Evil: Good luck!
