Am I understanding this Body Control Module issue correctly?
I have a 2000 Intrepid ES, with the 3.2L engine. Over the years I've had constant problems with the ATC system where I would get air only blowing out of certain vents and being unable to switch it. Doing the diagnostic, I get code 24, pointing to some type of actuator failure. My mechanic would replace the actuators, I would get proper vent control for a while, then they would fail again and I'd be stuck with air coming out of only one vent again.
I had a conversation with my mechanic about what is going on and here is what I understand: it's actually the BCM that's causing the actuators to fail, I think due to sending improper voltage and basically blowing out the actuators. The diagnostic sees this as just an actuator failure and doesn't trace it back to the BCM. Problem is, while you can get all the actuators you want, the BCM is no longer being made and (by their research) no aftermarket option exists for my car. The only option is to find a BCM from a junked Intrepid, but they're hesitant to go that route since it would also be a 20-something year old part and prone to the same failure as mine, so they wouldn't be able to guarantee or warranty their work. Apparently this BCM issue is a known flaw for the Intrepid?
Just wondering if anyone here is familiar with this issue and/or have found a solution to this problem, either some aftermarket BCM I don't know about or some site that sells OEM BCMs? Would there be any benefit to taking my car to the dealership instead of my mechanic since it's such a Dodge-specific thing? Thanks in advance.
