1995 Suburban rear air disconnect	Sign In

I have a 1995 Suburban with 180K miles that has a leak in the lines to the rear air. The front compressor is only 2 years old and works well and I don't want to spend the money to replace the rear lines. I got a quote of almost $400 to disconnect the rear air and just run off the front, wihch I understand will work OK. Is this an involved process? I see a fitting set online for $58 to plug the fittings where the lines connect. Is that all there is to it besides recharging? Do I need to disconnect power as well?

You aren't going to resolve this with a set of plugs if your lines are leaking. The rear lines are integrated into the fron and there is no place to separate them except right at the rear unit and yours is leaking ahead of that. The only way they are going to convert this is to replace all the lines to single type along with the accumulator. It would probably be cheaper to just fix the leaky line.

Even if you did this plan, it won't work ok. Its fine if you are sitting in the drivers seat with all the vents blowing on you, but anyone in the center seat will be sweating and god help whoever is in back because these things don't have good airflow back there. I feel your pain, I own the exact truck with the same issue. If you're going to do it, do it right. By the wat, there is only 1 compressor in this, just a second blower fan and evaporator. Compressors are driven by the engine and can only be one of them.
