1999 cavi Z24, Ok i was having a problem with no lights, I found the harness was all messed up. I replaced the headlight harness and i got my low beams back. I still dont have DRLs and only one high beam on the left. I put a new drl relay and still nothing the DRL light on the dash just flashes. OK now for the big problem When i drive down the street it seems that the ignition cycling or resetting. I will be driving and the radio will reset and the crime that comes on when you first put your key in will come on. This has me goin nuts. I had my friend sit in the car and i moved the harness around thinking it might be a wire but nothing. I then go back on the road and it starts doing it again. Any one had this problem or any idea what it could be
THis shoulds have been posted in maintance!
im thinking possibly a bad BCM?
99's do not BCMs......
You have a bad ground or missing ground if you only have one high beam. What year headlight harness did you get? I would check ALL your grounds if your radio is resetting.

The harness came from a 99, we just got a ton of snow so as soon as i can clear some i will check all the grounds. What is the box that is inside the right fender.
Inside the passenger fender is the pcm.

i found that it is for ABS. Could i have a bad PCM, I have no power at my DLC or my 12V constent to the radio but i have power to the cig plug. If i am dirving and stop at a light my cluster will spmetimes drop out but the car stays running and then the theft light will come on but the car still runs.
Yesterday I pulled out my PVM and found that it was a refub, so i went to the junk yard and got another one cost 35 buck and my old one. I got home and put it in and I had to do the theft relearn. I then started it up and took it for a drive and all the problems with the radio and cluster was fixed
. so i started to get on it a little and the car felt off, it didnt want to accerlate sometimes and the engine light came on. so got home and put it on the scanner and found that i hand a bunch of trans shift codes >:o. So after telling the guy 3 time that my car was a manual he still gave me the wrong PCM. So back to the yard tomorrow,
it was your PCM? will only a PCM from a 99 work?! i am having the same exact problem and mine is a 99 also!
please let me know asap!
Ya it was I went through the grounds and my power box and every thing. What made me think of the PCM was i was stoped at a red light and the RPM gauge would drop out and the theft light would come on but the car ran great. I am not sure what all years you can use the one i got was from a 99 cavi but it was not for a manual car and not sure if it was for a 2.4. It runs a little funny and and sets codes i got to go get the right one but all the other problem are gone. You will have to do the theft relearn when you put in the new one.
