My blower motor wont blow
bad fuse,
it can only be 3 things, a voltmeter finds this easy and every time.
bad fuse, bad switch bad, motor.
as we all know that includes all wires and connections, fore ever.
so you can check the blower , 12vdc on high.
if 12v there, and motor is silent the motor is bad or lost its ground.
to check that 100% apply 12vdc to the motor, bingo it works?
so no 12v to motor, must be bad switch, huh? after all the fuses is already checked(with ohm meter not eyes !)
so now i have 12v to the switch and no 12v out. must be a bad switch
easy huh?
ill now look yours up to see if there are other oddities.

ahh , up to 4 blowers, 2 front and 2 rear. fun but the 2 front are in parallel. and bingo, all 4 have there own FUSES !@!!!
forget that its rear and a/c only , what a complex car. no biggy
electrics is my game
i go to page 3 for HVAC, allh the heater, omg 2 relays 1 fan
the switch does NOT power the fan.
the switch only energizes relay 1, the ground relay
this heater relay pulls in and grounds the FAN.
ok 1/2 done.
next relay is Power side blower relay.
it gets 12vdc power from its very own 40Amp, Circuit breaker
the switch also ground this relay, it too energizes and bam
12vdc hits the fan
id bet the fan is good, and shock, no need to pull dash to get it out...
all that , in 5min flat , alldata.com
try it.
ask questions.
