Re: [MBZ] Climate Control unit 123
The blower motor is probably blowing the fuse. Uprate the fuse after replacing the blower motor if the fuse keeps on blowing after that. I have a spare used PBU if you want to swap it out.

Re: [MBZ] Climate Control unit 123
After you start the car try wiggling the ignition switch a little or turn is just a small fraction of an inch back toward off and see if it kicks in. I have seen a lot of times the switch gets some wear in it and won’t power the ACC. Other that that, the pbu is only part of the system. You also have the acc and blower control relays behind the globe box. Have to run thru the tests to see what the issue is.

Re: [MBZ] Climate Control unit 123
Good point. If it’s an 82 it probably doesn’t have the relocated and larger strip fuse for the blower motor. The original fuse may have melted down. -D > On Oct 1, 2019, at 12:35 PM, Curley McLain via Mercedes > wrote: > > CHANGE the FUSES ?

Re: [MBZ] Climate Control unit 123
The solder joints on the control unit circuit board can crack. If you're handy with a soldering iron, you can reflow those. I did that on my W123 to resolve some ACC wonkiness (been long enough that I don't really remember the symptoms though). Weird that defrost doesn't work, that is the "failsafe" mode AFAIK.

Re: [MBZ] Climate Control unit 123
I understand a vacuum leak could have an effect. But, when I try the CCU (push button unit) nothing happens. Wouldn’t that be more likely to be related to the switch? Keep in mind (and I’m just relying on the honesty of the seller), the previous owner said he was told he could “hot-wire” the blower to get it to work. So, I think he is saying that the failure is in the switch because the solder traces have failed therefore nothing is telling the blower to come on. Is that completely wrong? Donald H.
