This unit was installed on the car when I bought it used. 99 GTP. It wasn't secured under the dash very well and always seemed to hang down and get in the way of my feet. I constantly shoved it back under the dash. The signal seemed to get weaker and weaker so I figured the remote battery was dying. I tested it on the display thing at the parts store, the one you can press the button on your remote and see if it lights up. As I recall it didn't, so I changed out the battery. Didn't seem to help and now all functions have quit working completely. I was in the parts store the other day and by the display the remote is still working. When you turn on or start the car the led on the receiver antenna on the windshield would flash, but it doesn't anymore. I got down under the dash and looked and I had a wire broken. It's a very thin grey wire that runs to the receiver. There are 3 ports on one side of the brain that the receiver plugs into. One is for the LED switch, one is for an override, and one is for window unit receiver. The window unit receiver has 3 wires plugged into it and it looks fine. The override has no wires plugged into it but has 2 prongs, and the LED light has one wire plugged into a 2 prong port. I figured that the grey wire must plug into the LED light port since their are two prongs, but that doesn't seem to make any difference. I touched the grey wire to each of the override prongs, and it makes no difference. If I jump the two ports on the override I can hear the brain click like a relay. I've tried doing the reset procedure as the pdf suggests, but the LED on the receiver won't light up so I don't know what mode it's in. Anyone have any experience with this model?
