Seat heater has a mind of its own

[trotorx2]

Ok this must be a common problem as it happened with my '03 Z-71.
My driver side seat heater comes on by its self. The problem with the '03 seemed to come on the most after it rained. On my '06 it has started doing the same thing only it will do it even if it hasen't rained. I doesn't always come on but sometimes I will have to turn it off several times before it stays off.

I traded in the '03 with the problem still there. Of course this doesn't start till the truck is out of warrenty.

Anyone else have had this problem? Any idea's how to fix this? It's getting warm here in SE Texas...don't need a hot seat!

I have the exact same problem with mine and have had it since day 1. The dealer can't fix it. I have had the Control Modules reprogrammed, and it has been a little better, but it only happens after it rains. If it remains dry, no problems at all. ??????? I thought a new switch would do the trick, but that didn't work either.

Thanks for the words of encouragement there RI!

I can't figure it out. Once the switch switches on and off by itself it seems as if it dries the moisture out from within the switch or wires, and then it is OK. Weird how it only activates by itself after rain or moisture. Other than that, it is fine.

Sorry for the bad news.

Could the switch be weather proofed?

I am thinking of taking the witch out and using a little of the electric gel stuff (Sorry I can't remember the name) on the connections to see if that takes care of the issue.

Your talking about Dow Corning DC-4 we use it at work to keep moisture out of cannon plugs. It rained some today but I didn't have a problem. My '03 did it far worse than this truck. It would cycle thru the settings and wouldn't stop till it was ready. Very annoying in the summer.

I've been having this same problem, only when it's wet like you guys said, Weird.

If I figure anything out I'll let ya'll know.

It hasn't happened again for almost a month. I hope it stays that way.
summer is here on the gulf.

But it hasn't rained much down here either.

heated seat driving me crazy!

Whats up Guys!?

Lately my truck has driving me crazy. The driver side seat heaters will randomly turn on while im driving down the road. If I turn it off, it will turn on again within a few seconds or a few minutes. Now that its 90 degrees outside this needs to stop!

Anyone else had this problem? I assume i can just pull a fuse to stop the problem but that might affect other things also.

Any ideas?

Thanks in advance!

Yes!!!!! Gives new meaning to the term "hot seat"

The lights actual go crazy turning on and off continuously all by itself.

But yes the indicator lights do turn on. And it is not always the same...sometimes the butt and back turns on, sometimes just back, and at all different heat levels...AND mine does it even when there is no moisture in the air!
