Wierd Heater Issues

[harley 0]

Been reading through all the past threads about the heater blower problem and I think it's probably the rehostat that needs replacing.

 

However the blower has come on a couple of times recently, for nearly an hour the last time!

 

Am i right in thinking the rehostat looks like a thin metal card with a black plastic unit attached to the bottom where the white plug goes in? I've had it out and apart from a bit of dust it seemed in fine condition?

 

Also a friend seems to think this issue could be caused by a sticky relay?

 

Thanks in advance, Harley

Sounds like a rheostat issue to be honest. Your description sounds correct too.

 

Its fitted just next to the heater blower in the passenger footwell.

 

Cause could be internal within the rheostat, I personally had one that the metal strip came away from the unit that sticks out on one side, soldering it was a temporary fix however, as it progressively became worse again.

 

A new one fixed it. Try to borrow a known good one to rule it out. (just incase it is something random)

thanks. I have a friend with a ph1, I assume they use the same rheostat?
