Heater blower motor

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.

So I'm just starting to explore replacing the heater motor myself. Have read a few threads and watched a video or too - it seems daunting to a novice!

Couple of questions for the more experienced before I dive in if that's okay.

Reason for replacing motor is that when the motor is on full and wipers on full the fuse blows - everytime (this actually happened well over a year or so ago, I've been putting off tackiling it). I've been told this is most likely the heater blower. Is this true or are there other things I need to check first?
Radio has also developed static over the last year when previously it had been fine. Have reader that a failing heater motor can start to affect radio and have checked radio wiring and aerial which seem good.
So I guess first question is whether the evidence is pointing to the heater motor as the problem?

Looking online and at videos it seems there are many elements beyond the motor that can be replaced - do I need to go the whole hog. Heater in general works okay although it's either hot or cold with little in between. I don't want to do this job twice and we intend to keep the van for another 10 years+ so should I be replacing the resistor etc? Is this a like for like switch for a novice? 

Lastly, the wiper motor. Whilst the dash is out I'm thinking I should replace this as I've no doubt it's the original. Can't see any vids for this, is it a case of removing wires, screws, removing and fitting new (a bot like the starter motor) or more involved?

Thanks for any advice.

Replacing the fan is quite doable if you take it slowly and photograph every step.

I replaced just the fan, works fine now.

My advice would be to change the rubber heater hoses back there if they seem old.

I believe I can acces my wiper motor from the glove box with the dash still in.
