I am trying to find the ground point for the driver's side of the cabin. I've been dealing with electrical gremlins for a couple years now after the local dealer left the drivers window open through a monsoon weekend. Steering wheel controls intermittent, drivers mirror heat is weak, drivers fold function is too weak to fold, occasionally no power seat on the driver's side, spot light controls intermittent, and TPMS failures. Never any issues on the passenger side as far as seat or mirror controls.

So I'm thinking drivers accessory ground, the TPMS is the only questionable issue, but it happened at the same time, I've had the sensors replaced but they could not even program them. It started with just one going out, then progressed over a year to none of them, now I occasionally get the right rear (I think the other 3 have been replaced, and that might actually be in the right front position now.)

2015 f150 502a 212k miles.

Thanks in advance for an ideas, and possibly a picture of the ground location. I'm not as flexible as I used to be, it's getting difficult to fold into the foot well to look around.

 

From 2015 WSM, this might help.

 

My question is: Why and the H___ isn't the dealer who left the window open in the rain correcting the problem at their expense? I would make damn sure corporate is aware of this situation.

 

I'd be having the dealer who caused the problem fix it.
