Hi Scooty! Thank you for all you do ! 🤗Â
My Tahoe 2015 Lt blows hot air, A/c line keeps leaking from the same place . Been replaced 4 times , crazy ! Condenser unit been replaced once. Warranty its is over. Took it to the dealer when was 57,000 and didn’t tell what was wrong I think just recharged it with free- on .Buying time to the warranty to expired. Miles on my truck 92,000. I don’t  know what is next to do .Â
Take it to an air conditioning specialty shop (not a dealer) for diagnosis and proper repair.
Thank you !
Scotty explains how to diagnose an air conditioner in this video, at least as far as checking for charge and recharging. You can check for a leak like he does, but if you still have refrigerant in the system (gauges read pressure), it needs professionally recovered. You can rent the tools he uses from any auto parts stores. I repaired my truck's air conditioner with this video, but I also have some functional knowledge of air conditioners from engineering school. Be careful
Thank you !
