Re: Front blower not working

Next time it is inop- meerly whaaaaap the blower motor on its housing- if it starts (it probably will) then the blower motor is worn out- anytime blower is inop on all speeds- do the whaaaaap test. Blower armature goes off center due to wear- and lands in a dead spot- whaaaaaping it- moves it back on center and it runs- until it lands in that dead spot again....

same thing works with starter motors and fuel pumps....
