Default Why is my blower always on??

Any time I turn the key on the blower is on what ever speed the switch is on, regardless if the mode lever is in the off position. Do I just need new AC control?

If you are refering to the fan being on low speed in the off position, it's normal.

The idea is/was to keep air moving thru all the time so you don't carbon monoxide yourself. Thanks be to Uncle Nader.

Well that sucks, because my blower sounds like doodoo on low speed so I have to keep it on higher speeds.

Is it squeaking or sound like a card in the bicycle spokes? A squeak means the bearings are going away and the flapping noise is usually a leaf or piece of paper in the squirrel cage.

It actually kind of reminds me of a MK-4 automatic grenade launcher (minus a few dB). I should probably just take it out and look but that kind asounds like a PITA.

While the blower always going at low speeds, thanks to Uncle Nader is true, what you have written does not sound like normal operating procedure. The way I read that is you can have the system off and still turn the blower to any speed. Mine does not do that.

I did it with my '78 - it works to kill the continuous low speed blower operation.

fwiw...

I have stripped my car as much as possible for weight savings but I opted to leave in the blower motor, switches & odd continuous running of the fan.

I did this for HPDE track days/auto cross. During these events you have to have your windows rolled all the way up. The C3 is hot as hell in the summer time. Track heat & sun make it quite warm in the car. So, I like to be able to kick on the blower/vent to keep the cabin as cool & fresh air as possible.


(btw... I have routed out & removed the heater core) so, all recirculated air is (relatively) cool.

There is no 'OFF' position to our switches.

There is a post that shows how to install a different switch with an off feature somewhere...

I'd be willing to bet that you have a leaf or other debris in the fan shroud/blower area.


btw... 1st ID

True, there is no "off" on the fan switch but there is one on the controls to select A/C or vent. If he can get the fan to change speeds with this in the off position, something is not correct. In the system "off" position, the fan should only blow at "Nader" speed.
