Climate Control Wiring
Hi
Had my climate control unit rebuild completed. Before sending it out it was wroking. Put rebuild unit back in and did not turn on, reset 25 amp fuse and it came on. Next day did not work and reset fuse again but still did not work. Send unit back and rebuild team stated unit was fine after testing it for two hours. How do I determine if the wiring to the unit has an issue.
Thanks
Tom

It seems indeed that you have chosen to have the unit serviced at a workshop with little experience in fault HVAC finding.
I have sadly seen numerous examples of units that has been destroyed at so called reputable service workhops.
It is not unlikely that other components in the HVAC system has failed, this is by far more likely than a faulty CCU. However, without a working control unit, it may be difficult to do any fault finding.
What was the problem(s) that caused you to have the unit checked/serviced?
Cheers,

The wiring under the fuse panel has a locking mechanism to prevent the associated plug from dissengaging but it could be worth an inspection possibly the connection has been compromised in some other manner ...Bert

I guess Im confused. Did you say it was working before you sent the ccu off? If so why did you send it off and isn’t it obvious if it worked and then someone opened it up and now it doesn’t it’s something they did and not problem with your car?

I had mine replaced by ECU doctor because they are local to me in Ft. Lauderdale (no disrespect to Systems Consulting). It wasn’t doing anything wrong, but as a former naval aviator, I am a believer in preemptively replacing items that are due to fail. Nobody should be surprised when a 30 year old electrical box fails. At the worst possible moment.

That is where I ended up going. When it worked for a day and stopped they retested it for free. I think issue is in fuse panel maybe a bad connection as when I pulled out fuse to take unit out I had to pull a little hard to get it out. ECU rebuild my Cab module as well.

It’s an amazing shop. They removed and replaced my CCU for me and tested the cab controller at no extra cost. They told me my problem with the top was a worn ignition switch, they were right. They don’t do that work, so they didn’t benefit from being honest. The previous owner had receipts where a porsche “expert” shop replaced everything in the cab circuit trying to find the problem. They got paid for the incorrect work.
Thanks again Jorge (George).
