Suddenly, both my keyless fobs will only operate if held next to the rear driver's side wing window. I took the inner panel off (the one with the secret compartment) off and could not find the programming plug nor could I ID which wire is the antenna.

After I disturbed the wires, remote operated normally. After about three days, range was again very short. Wiggling the wires does not change anything.

Any ideas what I can do to troubleshoot/fix?

How old are the Keyfob batteries?

Try cleaning the pins on the connectors for the receiver.

I cleaned the pins & applied dielectric grease. No improvement. Remote works only if held near the driver's side rear window.

Which lead is the antenna?

The antenna does not have a lead, it is internal. You could open it, and resolder the pin leads to the board. If that does not work, it could be a bad electronic part in the RF circuit. You may find a bad solder joint if you look closely.

Thanks, Fred for the info. If I don't find a bad solder joint, I'll find a box in our local salvage yard, but that means reprogramming for the remotes.

I thought there was a pigtail to short out two wires to put the system in the learning mode, but I can't find that. I did the procedure a few years ago, but can't remember how I did it.

On the 91s it is on the same side as the box. On the 92+ it is on the opposite side.

Do you mean on the passenger side in the spare tire area?

BTW, if you are going to get a donor receiver, the 91s have gray connectors, the 92-93s have green connectors, and the 94-96s have black connectors. You can use one with green connectors in a 91, and it will work. I do not know if the 94-96 units will work in the 91-93, and vice versa.
