After rain, the door locks and alarms start cycling randomly, which can be canceled with the remote. It may go off 10 times in 2 minutes, or stay off for an hour. While parked the door locks cycle randomly. Tried to reset the passive lock with no luck. Someone suggested the BCM, which was replaced two months ago at a huge cost from a repair shop.

Frustrated. Any suggestions?

Thanks a lot. I was in South Carolina on vacation, worried about how to get the windows down or A/C working properly to make the fifteen hour drive with my kids.

My wipers radio and power windows will not work. How do I fix it?

Slap the side of the console. Your problem is caused by a poor connection inside the body control module buried deep inside the console. You can replace it, but it is very expensive.

I have a 99 Yukon and it's doing the same thing. I've taken her to GMC over and over again, and put in another $2000+. If you fixed the problem on yours, please let me know what it was... Thank you.

Check the fuse.

I have a 99 Yukon with 90,000 miles on it.

I live in south FL. Also, my air cuts out until you give it the gas, then starts back?? Just stops blowing when on cruise a while. Any ideas?? Where did you get yours fixed??

Thanks in advance.

Had the same problem. Ended up being the lock switch by the rear hatch. It will be to your right when you open the hatch. Just pop it out and disconnect it, and you'll be good to go.

That's what I did with my friend's new to him Yukon. It did the trick.

In response to 25 July, 2014. Sounds like something is getting wet when it rains and shorting out the electronics. A water seal is bad somewhere. It's just an aging vehicle. Good luck.
