small fan in dash

[dolfan13]

Did a search couldnt find anything. Replaced bulb for temp control area and now small sensor fan behind temp setting dials is running all the time.Has anyone seen this before?Thanks.

Sounds like a sampler motor for the temperature settings. Blows air at a sensor to keep the heat/ac at right temperature.

I hope you cleaned the fan and the temp sensor. I have seen some completely covered with dust.
Just recently I helped someone out, he could never set the temp right, mainly cold or hot.
It was not a stuck heater valve etc., just a dirty sensor.

Could I find how to clean this in my bentley manual? On mine it seems like there is no "medium" temperature, just arctic or furnace :).

No need for a Bentley for this, just remove it and it sits on the back,
how to remove and if you want to disassemble:

Always wondered why I seemed to get dust on the Climate control panel but nowhere else... Everytime I reckon I know all there is to know ...BANG... along comes something new...:D microfans... Sheesh!:D
