95 Suburban rear AC problem

95Suburban on Tue September 23, 2008 12:55 PM User is offline

Year: 1995
Make: Chevy
Model: Suburban
Engine Size: 350
Refrigerant Type: R134a
Ambient Temp: 75
Pressure Low: na
Pressure High: na
Country of Origin: United States

I have a 95 Suburban with front and rear AC. When I bought the vehicle the prior owner informed me that it needed a new rear evaporator and that all the R134a had leaked out (according to a local repair shop). Upon inspecting the rear AC evaporator, I noticed the rear lines were cut at the evaporator and crimped over. I would like to replace the evaporator and lines myself and then have an AC repair shop evacuate and refill the system. The evaporator shouldn't be a problem but how can I fix the lines? I've looked on the ACkits.com website but I'm not sure what I would need. Do they rent the crimpers? I would hate to spend $180+ for a crimper.
thank you,
Joe

Joe - the owner knew this, took you, should have informed you...

You are right, they should have told me. At this point there isn't alot I can do.

Some of these use two piece lines. If this one does, you may be able to replace just the rear sections with the evaporator. You might consider using something like this this...

High side filter

...as a line splice to effect a repair. You could seek out a local shop that can fabricate a solution like ACKits can in their shop.

Thanks for the reply. I will take a look at the filter.

I would go to the junkyard and get some replacement lines. A friend did that for his 2005 Grand Prix that had a split line and he saved a lot of money over buying a new one.

I wouldn't even think of used parts. Go on the aftermarket and find a line set and replace it with a new part. Replace the rear evaporator, expansion device, accumulator, etc. and you're in business.

No shortcuts.

Don't take this wrong (I have a 1994 Suburban) but your Sub is really only worth about $2500 (yes, I know someone originally paid about $40K for it, as original owner did for mine). So assess whether it's wise to invest a bunch of money just for rear air; since someone else already did you the "favor", maybe it's more prudent to REALLY seal off those lines to rear AC on this particular vehicle. What if you purchase lines and evaporator and find out the rear expansion valve is also bad?

I agree, I paid $1500 for the Suburban. Mostly because the AC didn't work and the brakes needed replacing. I would like to get the rear AC going if at all possible. It get's pretty hot in the back. Where could i purchase new lines?

Should be an all aluminum line running to the rear. Doubt you will find a replacement anywhere but a wrecking yard. But you might get lucky and find a source. While I prefer a new line as long as the line is capped and not corroded I think you could get away with a used line. Be sure to flush it before installing.
