O-rings again?

[Motorhead350]

My climate control fans keeps turing on and off at random while on the auto setting. I switch to vent and use the fan controller and this helps, but sometimes the fan will still shut off randomly for a few seconds. I can still adjust temperature. It's not "dead" like it was when the o-rings were shot.

I will check the connections later and I have changed the o-rings before, but it was with the "cheap" NAPA brand, not the ones we order, which what I suspect is slowly becoming the issue.

Does my assumption sound accurate or is this a separate issue?

Sounds like it's one of two possibilities:

1 - the electronics in the EATC are bad.

2 - the BCM needs to be replaced

The O-rings are not the problem.

new bcm is 70 bucks. i kept the old one, eventually i will get it sent off to jim for repair

It's not the o-rings, Dom. If you can live without a cabin blower for a week, send your BCM to Jim and have him work his magic on it.

...or get one at that pick & pull where you found all the window switches. The BCM should be the same in any CV/GM that has EATC.

I charge $25.00 for a repaired one. Free shipping. All I ask in return is that you send me your old one.

Alright. When I have time for this I will check it out. Until then, it's time to take the train downtown.

A standard sized blade fuse fits into the BCM connector. Do that and the blower runs on high any time the key is on. Temp fix.

The circuit board on mine went bad. Got a used one on ebay.
