Just seeing if any one else has ran in to this. My heater/air conditioner fan does not run when its wet or been raining. It will normally start, but if I stop then restart the car, the fan does not run. The other day it rained the whole day and it did not work any time. And of course the next day (no rain) its working great.
I am going to have the dealer look at it later in the week (they are calling for rain then). Seems to be happening more often, so I am hoping they can see it/find the problem.
Udate: This past Friday the heater fan stopped working again. Drove 30 minutes to the dealer and just as I got there it started working again.... sigh....
Went on to the dealer any way. Spoke with the service desk. She called the tech out. I started to explain how the fan was not working and he stopped me and said it needs a new fan, and that he can have it changed out in a couple of minutes.
In just under an hour, without an appointment the fan was changed and the car washed. There was no charge for the service.
Way to go Cary NC Smart Dealership!!!!!!
I have been having the same type of issues but mine seems to quit and restart when I hit bumps in the road. Since it is below zero outside I will have to wait a bit but it does appear to be a wiring connector problem. If I move the wiring harness around, I can make the motor start and stop. I assume the kicking of the lower side of the dash is doing the same thing. A kick is not a repair. I am guessing a bad connector and I will replace it to make the problem go away.
There have been some motors that were bad and they usually don't start back up. I am quite a bit past the warranty period with close to 40K miles on the clock.
I have been having trouble with mine this week. Today I took the fan out cleaned it up, per instructions off SCOA. Works a lot better now. It was awkward getting it out but I managed. I was going to bring it in the other day because it completely quit, but then on the way to the dealer it worked again. Dealership said they would not do anything if it was working when I brought it in. I filed my claim with NHTSA (www.safecar.gov) today.
No heat and defrost in -9 to 30 degree weather!
I had the same problem but without rain. My will stop every time I go to a small pothole what we can not avoid in Boston.MA. They just replaced the fan for the 2nd time. I hope this will end the problem.
