Default By-passing rear AC 1997 Burb - 06-20-2006 , 09:47 AM






Well,
Thanks to new england road salt ( I'm assuming ) my AC is leaking out
the rear condenser. Last year I replaced the pump and seals up front for
the tune of $400+/-. The pipes to the rear are , for lack of better
terms, corroding and seem to not want to break free of the condenser so
I took it to a dealer ( just for Shits & Grins ) and an AC specialty
shop ( highly reccomended by local parts stores ).

Both basically came back with high price tags and even if I do it all
myself it's still more than I think I want to sink into the truck ( 1997
K1500 w/140K ) as I will probably get an upgrade next year.

So my question is can I by-pass the rear AC someway? such as blocking
off the pathways to the rear ? is there a kit for this or an online
walkthrough? Any constructive ideas?

Thanks !

You can block the off and cap them up front if you want . The only
possible fall out is that the dual A/C system has a bigger compressor
and noy sure what effect this might have on front system when all of
refrigerant is forced through front system. It may if fact not be a
problem but it is worth mentioning.

I went through this on my 95 conversion van. The drier on mine had
rotted off. I found out that I could get an entire kit to replace the
rear A/C-Heat unit for around 700 bucks. That included the entire rear
core and fan system and hoses. it was MUCH cheaper than repairing the
original system.

http://www.cpcparts.com has a LOT of the individual parts for A/C units
in conversion vans. I would bet that the retro unit that I used would
probably fit is the Sub. http://snipurl.com/s26z
