Jimy Kraus Posted July 24, 2022 Share Posted July 24, 2022 The high beams on my '88 Reatta quit working. Both sealed beams are operable, as are all fuses and relays. The steering column stalk switch is also operable, but in panic of losing all illumination the first time in the dead of night now dangling due to my afterward anger. These cars are plagued with electrical problems due to technology GM used the public in place of a R & D dept. There's a reason they abandoned the touch screen by 1990 and returned to traditional knobs and switches. That thing is a collision just waiting to occur 1 Link to comment Share on other sites More sharing options...

Yes, Sorry I forgot to ask if anyone had dealt with the same issue. I am wondering what that headlamp control module located in the engine compartment does, and if that is where my problem lies ??

Ronnie Posted July 24, 2022 Share Posted July 24, 2022 The headlight control module is only for opening and closing of the headlight doors. It has no control over the lights coming on. I assume your doors open as they should? Your problem might be a broken wire at the headlight connector. It is a common problem since the wires are constantly being twisted by the doors opening and closing. I've had it happen myself. The lights are connected together by a common wire. If I remember correctly, if a wire at one of the connectors breaks it can knock out the light on both sides. 2 Link to comment Share on other sites More sharing options...
Jimy Kraus Posted July 24, 2022 Topic Author Share Posted July 24, 2022 Thank you. I will strip the plastic conduit back and inspect the wiring more closely to locate where there could be a breakage. Link to comment Share on other sites More sharing options...

Thank you again Ronnie !! 2 Link to comment Share on other sites More sharing options...
