2002 Altima AC stopped cooling, a relay issue

[miamicuse]

My 2002 Altima no long working. It blows but not cool air.

Took it to a mechanic and they said freon is fine and everything is fine but a bad relay. They call it a IPDO relay. They said the part is an expensive part and only Nissan makes it and it's $600.

WOW!!!

I am trying to see if there is an aftermarket part, or a used part, but so far no luck.

I typed into Google "IPDO relay" they asked me if I mean "iPod" or "ICBM"!

Is there a way to locate a more reasonably priced part for this?

That sounds made up frankly hahah.
I'd ask them for a part number or how they came to that conclusion.
You could always look it up in the factory service manual too.

My understanding is this part. Not sure of the part number. Looks like a grand central circuit board of a bunch of switches?

that's a hell of a lot more than a relay. Looks almost like an ECM. I'm not too familiar with that generation Altima, but I would think it would be labeled in the factory service manual. Or maybe another member will pop in and confirm.

It may also be a fuse/relay box, and that plastic cover pops off to reveal what relay they were talking about underneath.

Shoot, even if it IS that part, there should be plenty of those Altimas in the junkyard. They'll sell you what you need for a hell of a lot less.
