Hi Everyone,
Back in May, I lost the A/C in my expy, and I noticed a hissing sound coming from the rear A/C Unit. After some diagnosing, I concluded it was the evaporator and bought a used Rear HVAC Assembly.
I have the new unit hooked up, I've replaced all necessary seals, and the system still won't hold a vacuum.
I decided to fill it up with 12oz of refrigerant, and there is still a hissing sound coming from the exact same place in the rear unit, even with the new unit installed.
Are there any other places in the rear where a leak could spring? I'm at a loss here.
Thanks in advance,
Joe
