ive solved the constant headlight chime and the gauges issue i was having, but i do indeed still have the intermittent problem. ive only recently acquired this z28, so im not sure of its history (guy i got it from looked like rick ross
) but i can tell you it doesnt have an alarm, or at least i dont have a keyfob for one. i havent seen an aftermarket brain anywhere either.. ive replaced the door jamb switch already, and it works properly if you ignore the chime that remains when you take the key out. it still turns off when i close the door though so thats good. im still assuming thats an ignition column problem, so please correct me if im wrong.
so at this point im concluding that the intermittent problem is my RAP module, is there any soldering that can be done to correct bad contacts? ive only seen the guide for late model fourth gens, and many say that RAP modules are difficult to find, and expensive if you can manage to locate one. im no stranger to electrical work, and i can even microsolder if the need arises, but i cant believe there isnt a guide to solve this problem for early-model fourth gens. maybe ill write one up to kickstart my membership here
