I know how to remove my stereo unit. It is a stock unit in 1986 GT but my stereo loses signal all the time and when you hit the channel surf button it'll just go through static, but when I bang on the unit (via sides of dash)it will pick back up the stations. I wanna know how I can go about getting the wiring right or do I just need to replace the unit.seems like every other bump on the road helps me lose signal. I was using an FM transmitter but only during the times the radio would function. I need to figure out how to get it to function properly again.

Mine did that, and I had to replace it. You should be able to find a replacement via "The Mall" section of this forum, or you can upgrade to a later model Delco unit with a cd. I bought one from ReplacementRadios, and it works great. You'll also have to buy a replacement wiring harness which needs to be slightly modified, if you have the premium sound option.

Take the radio out of the car and take the cover off of the side with the circuit board. There is a connector that goes between two boards and if you resolder it you will probably fix it. To be sure, just resolder every connection on the board, it doesn't take that long.

Sounds like the tunner knob is shot. Pull the radio and send it for repairs, about $20. This is assuming you replaced the radio with a newer one like Fiero GM Delco, Delco AM/FM Stereo Cd player EQ Model. Gray front. Go to http://delcorepairs.com/....reliable and fast. Been there done that.

This is a common repair technique which also works for malfunctioning chimes... (see Ogre's Cave).
