Re: 156 heater motor keeps failing
Thanks for the responses.
I decided against going back to Caledonia and took the car to Reg Vardy Stockport instead. They did seem more interested in actually finding the underlying problem.
Their conclusion was that, yes the motor had failed again and the probable reason was that the area around the motor (under the dash on the passenger side) was damp, possibly causing the motor to short out. The dampness was caused by some missing grommets allowing water in.
So they replaced the motor again, let the surrounding area dry out and fitted some new grommets.
I'm crossing my fingers that this has really fixed the problem. It does sound plausible as I had occasionally noticed dampness in the passenger footwell area, especially after heavy rain.
