Check the plate on the current compressor and see if it has that Denso number on it.

OEM part number is 55056157AC - that might help your search for other options.

edit: I see rockauto has Mopar remans.. and I think there is a code for a small discount in the rockauto thread..

also, depending on what happened, you may need to replace some other parts as well.. if the compressor puked its guts into the system.

I'm really stressed out with school and not having AC is horrible for as much driving as I do daily, then having to figure out all the AC parts I need is really hard. I'm stressed out. I'd greatly appreciate some help.
I'm not sure what AC compressor to buy. There's only one $400 Mopar on Rock Auto. Should I buy the entire AC compressor kit for $400 from FourSeasons instead of Mopar? Do I need a full kit/would it be better? I also heard it's best to replace the condenser along with it, which one is best? I'd greatly appreciate some help. :)

That looks like a heckuva deal, not sure why it is so cheap.. with (both?) expansion valves and a drier.. you'll still need a pile of seals/gaskets for the fittings (can't say from the description whether those are in the kit)..

Do you have someone who can do the install? AC isn't really shadetree-mechanic work..

Includes the valves and seals as well. Think I should order that one?
A friend of mine has taken several of his cars that had AC problems to a friend of his who has a shop. He can install it for about $150.

Ask the installer guy; he's going to have to live with the results.

On the surface, that seems like a good deal.
But I know I'd hate to have someone show up out of the blue with a box of parts.

So the guy I found flaked out and everyone else wants about $800 to do the install.
I've watched a few videos and looked under the hood of my car, I'm planning on having the system flushed at a shop. Then doing the install myself. Any advice before I start?

Also in one of the videos I watched, the guy put oil on the new valves and seals. What kind of oil would that be?

That would be the correct refrigerant oil, which is called out on the underhood label..
Which you may also have to add to the compressor.
I don't know which oil a 2008 uses, but refrigerant oil can be very nasty stuff...

I really don't recommend DIYing the AC system unless you have prior experience AND a tech to lean on. Otherwise you're just going to end up throwing your money away. Just MHO, of course.
