Ac/heater blower does not work, could it be a fuse?

old post
the fuse boxes are 1 in cab and 1 in the engine bay
the A/C has 2 blowers,
one in the front of car, condensor blower.
and one in the heater cab blower.
both have fuses.
why is only a matter of using the schematic and a voltmeter
to see where the voltage fails.

does the A/C work at all
does the heater fan work?
need full evidence to go to exact cause. easy

REPLACE THERMOSTAT.IF ALREADY DONE.CHECK HEATER BLOWER MOTOR SEE IF POWER GOING TO HEATER BLOWER MOTOR.IF YES BLOWER MOTOR BAD.IF NO POWER GOING TO BLOWER MOTOR CHECK AC AND HEATER CONTROL FUSE AND CHECK BLOWER MOTOR FUSE AND RELAY IF ALL IS GOOD CHECK SEE IF POWER GOING TO AC AND HEATER CONTROL SWITCH IF YES THE AC AND HEATER CONTROL SWITCH COULD BE BAD.

CHECK BLOWER MOTOR FUSE AND RELAY.SEE IF POWER GOING TO BLOWER MOTOR YOU HAVE FAULTY BLOWER MOTOR.IF BLOWER MOTOR FUSE AND RELAY OKAY.IF NO POWER GOING TO BLOWER MOTOR BUT POWER AT AC AND HEATER CONTROL SWITCH. BLOWER MOTOR HAS POOR GROUND OR AC AND HEATER CONTROL SWITCH IS BAD.

REMOVE HEATER BLOWER MOTOR HOT WIRE BLOWER MOTOR IT.IF IT WORKS.YOUR AC AND HEATER CONTROL SWITCH IS FAULTY.CHECK HVAC FUSES AND CHECK BLOWER MOTOR RELAY.IF BLOWER MOTOR DONT WORK WHEN HOT WIRE REPLACE IT.IF ALL CHECK OUT GOOD.HAVE DEALERSHIP DO A DIAGNOSTIC TEST ON YOUR CLIMATE CONTROL SYSTEM.

CHECK AC / HEATER IGNITION FUSE IT WILL BE 10 AMP FUSE.CHECK HVAC BLOWER 20 AMP FUSE.HAVE BLOWER MOTOR HOTWIRE TO SEE IF BLOWER MOTOR WORKS.BECAUSE THE AC / HEAT CONTROL MODULE OR SWITCH COULD GO BAD WHERE NOTHING WORKS.

CHECK BLOWER MOTOR FUSE AND RELAY.IF BOTH GOOD.REMOVE BLOWER MOTOR HOTWIRE IT.IF DONT WORK REPLACE BLOWER MOTOR.IF BLOWER MOTOR WORKS.HEATER AND AC CONTROL SWITCH IS BAD.

Blower is used for either AC or Heater demand. If it doesn't work in heater mode, but work in AC mode then it is a problem with the Climate Control. If it doesn't work in both cases, then check the fuse near the front fender on driver side ( It is not in the fuse box). If the fuse is good, then it is not necessary the blower is burnt, but the blower regulator is burnt. The Blower regulator is underneath of the blower. It can be accessed from the engine side under the wiper motor.

Check your fuses. Is the blower not working???? When you turn your ac on do you hear a click????? Chances are if the heat and AC are not working, your blower motor is bad or your fuse is bad.

The heat selector switch in the heater control knobs is the only electric style in the group. The rest are cable driven. It may need replacement.

Heater blower motor resister is bad, replace, located under dash above heater motor.
