I have an 1989 Caprice and have a couple of questions about a ckt. The fuse blew twice and there was a burning smell the second time. Im assuming a short circuit somewhere in the ckt. On the fuse block the ckt is labeled as cktsys-clk or something similar. So far I've found it controls the dome light, horn, clock (therefore radio doesnt work), and power locks. Does anyone know what else this ckt controls or where I can find that info. Also is there any easy way to find a short besides ripping the dash apart and finding the bare wire? And im trying to get the radio out as well. Do the heater controls separate from the radio or is it all one piece and you have to unhook the stuff from behind? Thanks for any help.

I have an electrical diagram I downloaded off the internet for the 89-92 caprice 5.0L and 5.7L, but I cannot post the file here. If you give me your e-mail address, I can send it to you. I don't know of any other way to give it to you.

Sorry I can't help more.

my e-mail is atp5793@rit.edu. thanks for the help. i think it may be a bad radio or something else with constant power as the fuse blew while the car was off and while it was on.

Did the diagram help?

Yesterday, I pulled the cigarette lighter apart and have left it unhooked. The fuse hasn't blown since, so it must have been something with that. Thanks for the help.
