Don't fix whats not broken

Update*** after ben saved my day and fixed the heat in the taco, the module iss till missing the tension spring inside the blower power dial every once in a while I hit a hump and it kicks off, push it back in everything's fine...i have a replacement, but after 3 months of diagnostic and banging my head against the steering wheel I've now made an attempt 4 times in the last 24 hours to do the swap just to sit and stare not wanting to touch it. A wise man once told me not to fix what's not broken...anyone else ever have this issue.

 

Nope....as an Air Force Mechanic...we fixed EVERYTHING...throw caution to the wind and do it!!! Fix it Erika!!

 

Lol that's fair. Us Auto mechanics are the worst for fixing our own shit aren't we

 

Well I finally caved and replaced it.now hot is cold and cold is hot. I swear I'm far from. Stupid. It was literally just a straight swap. Unplug two harnesses plug two harnesses back in. And the module compatibility covers from. 05 to 2012. Is it me or is it the truck lol

 

well, its done and youre happy...

 

I am it's warm. Until someone in the vehicle sees it on cold sp they flip it lmao trucks gotta be quirky if I'm driving it I guess

 

You have the incorrect control for your truck. This is a known issue where they (Toyota) decided to reverse the polarity for some unknown reason.
There is a fix where you have to swap two of the leads on one of the connectors to correct the polarity issue.

If I find a link I'll post it here.
