Heater Fan Motor

Hi All,
I have been stripping out my +2 shell ready for some restoration work and I have removed the heater unit with the fan and heat exchanger. The motor works when connected to a 12v supply, however I dont want to rebuild the dash to find the motor packs up after a few weeks and have to strip it all out again. Is there a modern replacement or are these motors rebuildable/ servicable etc? The same applies to the heat exchanger.
Thanks

Salut Julian
Don't know about the fan motor but apparently the Ford Fiesta Mk1 heater element drops in. I certainly hope so because I bought one for mine. Might be able to tell you in a few days.
The fragile part is where the inlet/outlet tubes are soldered to the matrix - that's where mine failed after an over-enthusiastic mechanic wiggled them too much changing the hose. Well, I guess the solder joint must have been weak already, and access is really difficult?

My heater fan motor in my S3 was replaced by a firm during body repairs back in 2001, but their auto electrician was not a bright spark.
The motor he installed was a two speed motor, (as I'm fairly sure the original was.) It did not need a dropper resistor but had/has two speed working inside. Unfortunately the dim sparks wired up only one speed and furthermore clipped off the surplus wire too close to the body of the motor to solder on or clip on an extension wire!

Hi Julian,
I have heard that the fiesta unit fits in. either way it might pay you to see if you can get the brushes out and check that they are not worn down to the wires. I'm sure that the amount of use the fan actually gets, then new brushes hopefully will see it last a life time.
Good luck!
Kind regards

Picking up an old thread ...
I replaced the brushes of my fan motor in my Sprint. The motor runs now but the next problem are the bronze bearings. Depending on speed and position the fan whines. Heater fan motor and radiator fan motor are not interchangeable (different axle and speed). My questions is:
Has anyone found a better replacement part or solution ?
Whats the fan speed (rpm) at 12V ? Are there suitable roller bearings ?
Thanks Peter
