There is a resistor in the top of the duct work behind the glove box. Check the wires on the resistor with an ohm meter. They all should have continuity. If not, it is bad. Speed 4 is wired directly with no resistor. The three lower speeds are set by adding more resistance from the resistor. My 93 Eurovan and my 92 BMW both had the same trouble and I fixed them both with used units from a junk cars; or you can buy them new from the auto parts store.

Heater blower does not work


Four possibilities. One is the blower motor fuse in the fuse box to the left of the steering column. One is the fan switch on the dash, One is the ballast resistor under the dash below the glove box. Third is the blower motor itself. The first three take a few minutes to check out. Replacing the blower motor requires an hour and a half if it's done by someone who's done it before. I've replaced a dozen of these.
Good luck

all speeds go through the resistor except high that is why it will work on high you are bypassing the resistor if you are sure the resistor is good it has to be the blower spped switch on the dash

1993 VW Fox a/c blower does not work on 4 (high speed) It's not the switch for sure because I've by passed it and still no high speed.


This is not the resistor. There is a relay on the fuse board that makes the fan's full speed work, it must be replaced or refurbished. Any additional questions, please email me paulojosebaptista@hotmail.com Greetings from Brazil!

Honda Accord 2002 heater blower control works only in the high position. The 1, 2, and 3 positions do not work but the high (4) does.


The heater blower is normally controlled by voltage sent to the blower via a resistor network.
In this case it seems that this unit also called the fan resistor is defective.
I assume that 4 is the position where the blower is running HIGH and in this position the blower is powered directly without using resistor for lowering the speed of the blower. In step 1 - 3 the blower is powered via the mentioned resistor network.

In my opinion the resistor network is defective.
Replace it !!!!.

Heater blower switch will only work at possion 4


Underneath the glove compartment on the passenger side is a cover which must come off,2 plastic screws holding this cover.Underneath you will find a 5 pin connector[big plug] connected to a white connector in the blower fan housing.This is called the fan resistor which controls the blower fan speed.Unclip the resistor out the housing and renew.Your problems should be solved..regards

Fan stopped in vw t5 intermitently comes on low when van driven a while


You may have an issue with the temperature sensor found at the lower radiator hose. Pull out the plug connected to it and see if the fan would run continuously while the key is on "ON". If it does run, have the temperature sensor replaced and if it does not, check the relay and the wiring that goes to the fan.
