93 98 Regency Electronic Problem

[P35A]

Wondering if anyone has any idea what's going on here: I own a 93 Olds 98 Regency Elite, about 3 months ago all the electronic accesories started going crazy beginning with the automatic climate control. Now the climate control, radio, keyless entry work when they want to. Somtimes Ill get the radio and a/c to turn on, but I cant adjust any of the settings. Sometimes different warning lights come on such as the "Service Engine Soon" and "Check Oil," etc. But nothing is wrong with those systems. It's like the car is possesed or something. Does anyone have any idea what's going on? Maybe theres a faulty control module or something? I dunno. Please help before I get an exorcist for the car. Much Appreciated.

Hi Dan,

Same thing happened to me a year ago on the same model. Check the BCM (Body Control Module), its the Computer that controls all onboard electronics. It tend to go bad after so many years. The part retails for about $200 at the dealer. Hope this helps. Jon.
