09 LTZ seat issues

[Chris Camacho]

I'm familiar with forums, but this is my first post on this one. I know that's frowned upon with out introducing my self but I'm having some issues. I picked up this 09 Tahoe 4 days ago and there are a few issues I can't chase down.

Neither the heat, or cooled seats work on both sides. No power functions work on the passenger side but they do on the driver side. I've checked all the fuses and circuit breakers and all check good. I un- connected all connectors underneath both seats, no corrosion, signs of burning or pushed back pins. Can anyone point me in the correct direction? Thanks ahead for any information you may have!

do the lights on the buttons on the doors light up?

Yes they do, all 3 levels for all 3 functions

I don't know if it helps to know you're not alone but here goes. I thought my AC driver's seat worked earlier in the summer (just bought the truck well used on July 4) but don't think they've worked for a while. Then I had my wife in the car and the temps got below 80 so she needed the heated seat. (trust me)

It didn't work. So I tried the driver's side and that didn't work either. The lights on the switches light up like they should but neither front seat appears to have heat or AC. Haven't tried the second row yet for heat.

Both seats have full motion. I tested any fuses I could find that were labeled as having anything to do with seats or HVAC and any I couldn't understand the labels on. All good. There has to be some common point of failure.

I found a post that talked about a burned pin on the heated seat controller under the front passenger seat. I took a look and sure enough it's burned on mine. I'm in the process of fixing that now.

This is someone's repair on the wires to that connector.

This next picture is the connector too.
