Do you have power to the switch? Do you have power to the fuses? They may not be blown but they may also not have power. Not a likely scenario but possible. First look for power to the switch. No power trace to fuses. Next check if switch is getting power doe switch send power. Does blower motor receive power after you verified that switch has power. Is the switch from the dealer or a/m? Try these things first. If the switch is used than the switch is probably bad. Also there is a resistor on the blower motor that can go bad and that could be the problem.

91 Astro Van, Heat/AC Blower not working....replaced switch, fuse, motor


well here's your fix next to the blower motor is the resister that controls the different fan speeds the resister burns out but before getting the new resister unplug the resister as the connectors over heat and at time also need replacement

My Blower motor for my heater on a 99 ford escort is not working.Is it the motor or resister that is gone??the fuses look ok where is the resister located can you send a diagram


look in passenger foot well on blower case for 4 wire connector.



Behind right side of I/P, A/C-heater plenum


resister bad would still allow high speed. may be blower motor.

  • The blower motor does not operate/does not operate correctly
  • Open fuse.
  • Tripped circuit breaker.
  • Circuitry open/shorted.
  • Heater blower motor switch (18578).
  • Heater blower motor switch resistor (18591).
  • Blower motor relay.
  • Blower motor.

Carina E L Reg. my heater blower has stopped working,Cant demist or heat. I have checked fuses as described in the manual and they are ok HELP please


If the engine compartment fuse #105 is OK, next 2 items are :

1. Blower motor relay. This is in the same fuse block as the flasher, under the dash, about in line with the steering wheel column. It should have a cover on it, so it will be black, and hard to see.

When you pull it, you can bypass the control panel operation of it, by jumpering the normally open contacts ( show below with the red line )

If this does not work, the next thing to check is the blower motor resistor, mounted in the blower duct on the passenger side :

The right hand side of the picture, is the passenger side kick panel where the fuel inertia switch is at. The wiring pigtail shown goes to the blower motor resistor, which is towards the left / driver's side.

The resistor usually goes out, with only the high speed part working, but you could have a case where all are out ( seen it happen before ).
The black wire in this harness should go directly to ground ( check with a meter to the ground lugs behind the passenger side kick panel ).
A loose / missing ground to the blower motor resistor will also give the same symptoms of a blown resistor pack.

1997 Dodge ram 2500 deisel. Blower fan wont come on. replaced climate control module and fuse is ok. Is there an inline fuse or relay I'm missing?


if the fuse is ok your next step is to see if you have power at the heater fan switch,if you do then the next thing is the heater blower motor resister it is under the heater assembly,that is what gives you different speeds,
the last is test for power at blower motor to see if it is faulty
