Heater blower motor

Post by Komet_V2 »

So, any movement through the blower settings doesn't activate the blower. Can it be anything other than the blower motor. When it went, there was a short time burning smell, say a minute.

Could the motor be fine and it's a fuse ?


There's still air coming into the cab, hot or cold, by moving the direction levers to cold or hot. But no control over strength.

highly likly the motor, you can feed 12v direct the speed 3 wires which bypasses he resistor if that does nothing your motor is open circuit ( or the wiring which is unlikly. if you get lots of sparks your motor is shorted and you will find the fuse probably has blown.

It feels like a big job but in reality uninitiated it took me 3hrs , worst bit is the anti tamper bolts on the column if they have never ben replaced with normal ones.

Thanks for the reply. Bought a new blower motor and left it to the garage.

Disappointingly, radiator fan not kicking in, either. Getting that checked, too. Probably more important than the blower

It temp guage is to believed, van seems more susceptible to getting hot faster without any obvious reason

might be worth doing a coolant flush and change if it hasn't been done in a while; always worth washing the rad out fully and keeping an eye on what comes out; Also if thermostat hasn't been replaced in living memory is also worthwhile; but these jobs can always go pear shaped with garages who aren't careful or aware of the possible failure modes

shame you left it to the garage, it's not a hard job but a pro will probably spin it out. if they charge more than 4hrs labour then they are pulling  a fast one. 

Having the dash out is a good opportunity to replace the washer hoses and generaly inspect the wiring. 

Chances are the garage may find damage on the heater box flaps or cable clamps, neither is insumountable with a little bit of inginuity.
