Blower fan stop working after car wouldn't start

[jasonnovak]

On Friday we had a really cold morning and my car wouldn't start, even tried to jumpstart it. So today I put it on the charger and got it started, however the blower wasn't working - it's never had this problem before. I have a 99 GTP with digital climate controls. I can hear the doors etc clicking as I go through the modes and toggle between auto/manual control, but no fans. Checked the fuses in the glove box and look good. Strangely one fuse I see in the manual doesn't have a fuse and only a contact on one end, must have been a last minute change.

Any suggestions - seems like strange timing this happened right after a really cold day, is it possible the battery is bad and it's not turning on due to voltage? Seems ok. Maybe jumpstarting killed the resistor/motor? Need to beat on the motor?

Test for power at the motor, even apply 12volts and a ground to the motor and see if it turns on.

Hey, checked it out this morning at did have voltage at blower connector. I also noticed there was a hose that was supposed to be going into a hole in the blower housing held on by a big loop around it that wasn't in place, stuck it back in, probably out for a while. Maybe a drain?

In any case still didn't work, so I hit it a few times and it started working. A sign of a failing motor or just froze up in the cold? Been through a lot colder...

Motor is probably on its way out. Doubt it actually froze.

Motor is likely on its way out. However, if you haven't done the cowl fix yet, it is possible that the motor froze. Water from melted snow or car-wash or whatever, could have dripped into the motor and then froze overnight. It can freeze. I know from experience. Look into doing the cowl fix.
