TPMS question and wondering

[Jrscherer]

I've noticed lately, now that it's getting warmer, and the air conditioning being used that when I am driving on the freeway for a bit it will start to go on. Now if I turn off the A/C, it will turn itself off. Has anyone else seen any problem like this before?

I've read about a issues with the TMPS (and had a few myself) but never a on and off again sorta thing. Sounds like there mihgt be some faulty wiring in your car. I'd take it into the dealer and have them sort things out for you.

Doesn't the TPMS only deals with tire pressure???
