Power Locks don't work when key is out of ignition, and radio doesn't work at all. ALSO RPM needle is still fluctuating after throttle bore actuator.

After getting the throttle bore actuator cleaned the RPM needle still continues to fluctuate causing the lights to dim and come pack on. I took it back to where I bought it, the "mechanic" then plugged in his computer reader to my car, I tried to open the door to get inside and then he said I messed up his machine by trying to do so. So now my radio doesn't work at all, and the power locks don't work unless the car is on with the key inside. I'm so lost and stuck and now my car is in worse condition than when I brought it to him.

I checked all of the fuses both under the hood and below the steering wheel and none of the fuses are blown or burnt. The "mechanic" said he just needed to get his computer fixed so he can fix my computer. But my question is how does that get done? I tried to go to autozone but their tiny computer didn't even come on when he connected it.

Opening the door while he was connected to a scanner shouldn't have hurt anything. Since your problem seems to be with an idle issue, I have to ask if the idle air control valve has been checked or replaced. Also, has anyone checked for vacuum leaks?

As far as the radio, what needs to be done at this point is to check to see if there is power where the power supply plugs into the back of the radio. You may also want to check to see if the fuse is good by removing it and checking it for continunity. Many times a fuse can look good but be bad.

Finally, I am concerned that the scanner from AZ won't turn on. That could indicate a problem between the computer and the port. It could be a wiring issue or a problem with the PCM itself.

Can you tell me what the mechanic plans to do once his scanner is repaired? Has he told you anything?

He just told me that once the computer is fixed he can read the codes to see why the RPM needle is fluctuating. And at the same time fix my radio and power locks. At this point I'm very frustrated with this man. I really wish I had the money to go to chrysler and have them look at it. It sounds like a simple fix for the idling issue but I'm really concerned about my radio issue. I can't live without my music. I hope the radio is a simple fix as well.

The radio could be a simple fix or it may be bad itself. You also mentioned that the door locks don't work. Did the radio and the locks stop working at the same time? If it did, it could be something as simple as a bad ground or it could involve the body control module (BCM).

They both stopped working at the same time. How do you fix it or check for issues? If possible could you add detail because I'm going to be relaying this information to the mechanic. Also could you explain the fix for the idling issue as well? Thank you so much!

Have him check the idle air control valve (IAC) to see if it is operating. Also, he should look for vacuum leaks.

As far as the radio, something tells me it is more than just a bad connection. However, you need to start somewhere. I would have him check to see if there is power to the rear of the radio. If there is, chances are the radio is bad, If there is no power, he will need to trace the wiring to locate where the power is lost.

I have another small question, I got new spark plugs and wires, and a new air filter. But what other key components needs to be changed to last my car for a little while longer? Basically, I guess I'm asking what is the list of things that needs to be serviced or replaced during a tune up? Like I said I already got the new spark plugs and wires and air filter but what other necessary components need to be taken care of? Thank you. One more questions: What does the PO700 code mean?

With today's cars, there isn't as much needed as years ago. You already have the plugs and wires. If there is a distributor, replace the cap and rotor. Also, check or replace the PCV valve and fuel filter. I always check things like belts and hoses to make sure they are good.

Okay, the PO700 is nothing more than the TCM telling you there is a problem. It, in itself, means nothing more than you need to get a scanner that can communicate to the TCM. Now think of it like this. The input sensor realizes that the engine is revving, but the transmission isn't accelerating. This can be caused by something as simple as a plugged trans filter or the clutches could be out of the transmission, or it could be an electrical issue.

There are over 100 codes for the TCM. I hate to say it, but I really doubt that AZ has a scanner that can truly read the TCM. In this case, I think you need to have it looked at by a dealer. Otherwise, you may end up spending money on parts that are good. Just for the heck of it, make sure the trans fluid is clean and full and let me know what you find.

Let me know. And, until we are sure of the cause, you shouldn't drive it.
