I hate to think it and say it but I have seen where when all else is eliminated, it turns out to be a leak at the evaporator. I did not see a thread about your a/c problems but has that been looked at? Not that you can see it till you rip it out of there.

Don’t put that voodoo on me Ricky Bobby!!!!

Sorry, but have been there and done that so many times. Lots of a/c work when I was in KC, Mo.

It is what it is, if that’s the case I’ll fill the AC right before a potential buyer comes to see it and then kick the truck to the curb…..





Jk anything can be fixed, but I don’t think that’s the issue, I’m wondering if it leaked out and I just haven’t inspected it well enough with the black light to find the leak.

I know you likely know this, but refrigerant is heavier than air and when checking for a leak you need to sense at the low part of the fitting or seal. I used to use a lit propane cannister that had a flex hose that I ran along the a/s lines and components and watched for the flame to turn green. I always that the battery powered sensors were 50/50 accurate. Plus, the lower the charge/pressure in the system, the slower it leaks. Found a few evap leaks by shoving my propane flex hose up the condensation drain.

Happy new years ladies!

New year and same old tahoe with no G** D*** ***** F*****n Air Conditioning!

No idea where the leak is this time but its definitely low on r134.

hey bro, happy new years

shoving my hose up the condensation drain.

That’s naughty!

I’ve never thought to do it with a torch, I might just have to fill the system back up and once again look for leaks while wasting r134. Good news is I just spent $500 on a 30# tank of it lol.

Seats? Most of the dirty deeds have been done everywhere else BUT the seats in that truck.
