The fan switch for my heater only works on 3 and 4. The first two do not seem to work.

 

Any ideas?

Your blower motor resistor is bad. It slips into the bottom of the blower motor (behind/below the glove box) and is very easy to change. The dealer wants some astronomical amount, I usually just grab a handful from the junkyard and after a couple tries, end up with a good one.

sounds like a broken fan resistor pack.

Skip outlines where it is and how to test it here: http://www.ultimatesubaru.org/forum/showpost.php?p=282650&postcount=9

 

good luck

I just picked up a resistor pack from Autozone today for a 1986 GL. The price was $41. More than jy, but I know it will last for a long time.

Thanks, for the info. I will try and do it this weekend. I am not sure if Pull and Save is open on Monday or not. If not I will do it next weekend.

 

Always find the help I need on the board here.

 

Thanks,

Just to be a little contrary, I have experienced a less-common failure: The fan switch itself going bad. One of ours only works on "2" and "4"... unless you press in on the knob/shaft and then they all work.

 

Just a thought.
