AC help

Hi all. I have a 89 Grand and have the AC components on the inside but nothing under the hood. (V8)


Can any one post a diagram of parts needed under the hood and layout. Only have the compressor mounting bracket in place previous owner removed everything else.


Thanks

I have misc. A/C parts, I installed it on my J20 which never had A/C, I still have parts from other vehicles. You can buy the condenser, dryer, and expansion valve new, and maybe the compressor. You might have to find a shop to make the hoses.

I think wagonmaster sells an AC hose kit now. Price seems reasonable too. Wish I knew about that before I did my system and bought the crimping tool, fittings ECT.

There isn't much to it. There's a couple of hoses from the compressor, one goes into the cabin to the evaporator, and the other goes to the condenser mounted near the radiator. Also two 1-wire connectors for power (orange?) and bypass (black?), I think.

Do you also not have the hardline with the sight-glass on the passenger inner fender, or condenser mounted near the radiator?

Which mount do you have? Since it's an 89 I assume it's for the ovoid Sanden unit, not the rectangular York unit.

I have heard it said, on here and other places:

I have no experience to help so take this with a grain of salt. Mine does not work and I plan to fix it in the next 12 months so I read a lot of posts on A/C here and it is a common thought amongst some folks.

Check out my build thread and accompanying Flickr album. It may be useful to some extent. I did "remodel" the factory air, but updated to a Sanden compressor and made the system 134a compatible. I had new hoses made using the metal parts of the originals. The rest of the front parts were new repops of the originals bought of the net. Deleted the sight glass and moved the low pressure switch from the fender to the drier. SonaraEd on the other forum helped me a lot with it.
