The blower fan for the rear air stopped working suddenly one day. No
bad noises or such.Checked the fuses under the dash and all are fine.
When trying to turn it on at the front control panel or the rear
control panel, you can hear the relays clicking in the back. One time
the blower suddenly turned on and all controls worked fine for a couple
of days. Now have nothing again. It is might cold here right now and
rear air is pretty important. (1.2 degrees farheneit!)
My question is what is the most common cause of this problem? Where
would be a good place to start troubleshooting? I figure the most
likely causes are relays (there is 4 near the rear blower motor)
wiring, and switches. How can I narrow this down quickly, so we aren't
freezing trying to fix it too? ;)
Thanks in advance!
