The resistor has a thermal limiter in it, if its bad, it cannot be reset. The blower motor may be bad causing high amperage, burning out the limiter. At the resistor,Ck if there is power at the GRAY/BROWN and GREEN/WHITE, and BLACK/GRAY wires, they should. If not CK the Violet/Orange wire, it should have power.If the Violet /Orange wire has power, but the others do not the limiter is bad and it needs replacement (resistor) If all have power, then when gounding each wire (except the Violet/Orange wire) the blower should come on

Heater only works on high speed replaced switch and resister and relay


Did you check the hvac 10 amp fuse? There is a 30 amp fuse for high and a 10 amp for the lower speeds.There is also a blower motor control module.

My Heater Blower just stopped working. Checked 30A Fuse its ok. What could be the problem


Hello...

It could be the Blower Relay. If it only works on different fan speeds, set by the switch, it also could be the Blower Resistor.

Good Luck

Last week the heater blower motor stopped working on intermediate speeds and would only work on high. Today after working for a little while on high I lost all speeds of the blower motor. Is it the switch...


resistor for sure, the switch would have caused all speeds to fail as it only has one moving contact but the tapped wirewound resistor is a common part for this fault.

Blower motor does not work


I had the same problem, replace, replace, replace. Check, check and recheck. What I found was the blower motor resistor, located in the blower squirrel cage area, two prongs and a curly wire, was bad. Took the new one back, (it ohmed out okay, continuity ok, all ok!) replaced it with another, and Bingo, problem solved. Frustrating to say the least. After two relays and a blower switch, and test, test and retest. It was a faulty resistor. Made in Mexico. And no guarentee, even though new, it works. Trial and error. Even the dealer parts are Honcho en Mexico. Thanks NAFTA. You gonna make us all welfare babies.

Heater Control Switch Only Works on High


It appears there is a resistor block there, either at blower connection area, or at firewall area on passenger side under cowl somewhere. It is quite common for blower to only work on high when resistor goes. Look for block, or base, 1-1/2" x 3" approx. with electrical connector to it.

Heater Control Switch Only Works on High


Your problem is probably a part called the heater resistor block or board. When this part burns out you will only have high speed on the fan. On my 1999 voyager it is located on the firewall and it snaps in a hole in the firewall. This is under the hood behind the alternator.
Mine had a multi pin black plug plugged into it. Unplug the plug and
you should be able to pull the block out insert new block and plug plug back in and it should come to life.
