I have a 2008 XB manual transmission. The other day while driving to work the heater fan stopped working. Then I lost both left and right signals. The power steering went next, and that is when I realized my alternator was bad. I have since changed the alternator and battery. Everything seems to be working except the blinkers and heater fan.

Why would my blinkers and heater fan not be working? All fuses have been checked.

 

I know you said all fuses have been checked, but did you check the under hood fuses and fusible links? Just have to ask because people forget about the ones under the hood.

 

Yes, I checked the fuses under the hood and under the driver seat dash.

 

Do you have power at the fan connector?

 

One possible way an alternator can stop producing power is by.makimg TOO MUCH power.......when the alternator malfunctions and produces too much power, the PCM commands the alternator to stop producing power.

Producing too much power could be the cause of your vehicles turn signals not working as well as the blower fan not working.

First, regarding the turn signals.....do you have hazard lights? If the answer is yes, you need to replace the multifunction switch.

Second, regarding the blower fan......test the connector for power. If you have power, replace the blower fan.
