Hi Folks,
Odd issue with my heater switch. Since owning her the fan works on all settings but ONLY when DEFROST or MAX are selected ?
Any ideas ? I have replaced the rubber maze like seal behind the switch. Could it just be dirty contacts ?

I suspect it's an issue with the electrical contacts in the mode control switch. I recently fixed an issue on 5052 where the fan would continue running even if the mode switch is off. The culprit was a broken plastic tab that holds down the contact. I was able to find the disassembly instructions online.

Thanks Andrew,
I have only just got the centre console back in after a Bluetooth chip addition to the original radio. Do you recall If the console needs to come out to get the switch out ?
Hopefully not..... Time to get my wife with her small hands back in there

About has to be, if all speeds work in any mode, because of the way it's wired.
It can be done. Small hands will help...and a long forearm.
Aligning it all up while starting the small mounting screws is the greatest challenge doing it that way.
I can't remember for sure but I think when I reinstalled my switch it did something like that I Had 2 wires switched around But i am just not sure at this point because I have done so much on this car hard to remember.
It would be worth a double check of the wire positions on the Mode sw.
