The heater is getting warm but not blowing, has the fan motor gone? can it be replaced without removing bthe complete heater? I have checked the fuse and switch so neverything is pointing to the fan motor unless you have any ideas please? cheers Tom

Do your 'Windscreen Wipers, Washer Motor & Instruments' work, because they run on the same circuit as the heater.

You could try cleaning up the fuse box as the rear terminals do get very rusty with age and it could just be a bad connection.

But if the fan motor is dead, then the whole heater assembly will have to come out to be stripped down. Pretty easy task though.

Instruments workwipers etc. work, fuse box o.k. so looks like fan motor.
Does the dash have to come out ? got anothercar in my garage at present so may have to take it to a mechani c
How much will it cost? regards Tom

[taffy1967]

Just buy a Mini Haynes manual and do it yourself and no the whole dash doesn't have to come out.

Take a look at this thread as I explained what needs doing here: -

Cheers Taffy, just been on the minispares site must be the most expensive bit on the car! £247!!!!!! just for the fan motor.
Gonna take it off and if its fubared i'll have to look for a second hand one.

[taffy1967]

Yes I remember sourcing a good second hand replacement heater fan motor for my sisters old Mini.

It cost no more than about 20 quid from my local Mini specialist who stocks new and used parts.

Before taking the heater out, check the switch is Ok.
I had an intermittent motor a few years ago and it was the connectors on the switch had become loose. I crimped them back into shape to make them tighter and the problem was solved.
Try bridging the wires to eliminate a faulty switch.
Also check the earth???

I had a similar problem last week. It turned out the fuse "grips" were an ever so slightly loose fit : enough current was getting through for all the instruments on the circuit except the fan motor, which I guess has a much greater demand. Solution was to pinch the tangs of the grips to make a tighter grip on the fuse.
