Has my R32 Climate Control Unit met its demise?

[TurboTapin]

It was pouring rain Friday night, and my windshield started fogging up. Went to turn on the defogger and to my surprise, my climate control doesn't turn on. The recirc and defogger light strangely stay lit though. I'm presuming it's dead, but has anyone had this before and resolved it?

Looking this up online, I found a few mentions of bad solders on the connector between the two PCB's or the connector itself being dirty. I resoldered the connector on both ends and cleaned it but it's still not powering up. No other dry solders that I could see or any components that were toast. I found a few used ones at ridiculous prices (600-800$ CAD). A new one is 790$ shipped to my door. So as mentioned, before I order a new one, has anyone seen this and fixed it?

See if you can power it up on the bench.

Already done, along with confirming all the wiring to the unit checks out. It's more of a wild goose chase in hopes that someone else found a failed solder, bad component, etc. within the unit itself.

I have a feeling I'll have to just order a new one.

How come you can get this in new? Is it part of the heritage program? Personally for a hundred dollars difference I wouldn't gamble on another used one.

It's just a regular Nissan part you can get from your dealer or online. Part# 28525-05U12. I just went and ordered one as I don't see any other option. Cheers.

For that price I might go buy one for just in case

Just for a good chuckle. I received the new climate control yesterday and just before starting to remove my old one, I decided to try it again... it worked and has worked since haha. I'm keeping the new one on the shelf as I know it will repeat itself again at some point.

I’ve seen a video on you tube where the issue is just dry solder joints and once you fix them the unit lasts forever

Yes, I mentioned it in my first that I did everything that is mentioned online (Redo dry solders, clean connector between PCB's, etc.) and unfortunately it didn't solve it. 

It crapped out again earlier today, so I replaced it. I'll keep the old one around to repair it at some point.

Ah damn. I might grab one myself because mine works most of the time lol

It was cheaper at Trust Kikaku then it was at the dealer with my 15% off. No clue how, but I won't argue. Here's the link if ever you need one. Cheers.
