Hi, I've searched on the forum briefly for this answer, came to no avail.
On my Rover 200 bubble, My heater fan speeds doesnt work at all, (The knob with 1234 on it) I've changed the switch itself from an known working one on another rover and have tested working on that car.
Fitted said switch from working car to mine and it still doesnt work at all??Can anyone shed any light on this?
It currently has suspected HGF but I would like to get the heater fan working before changing the HG after a garage "bodged" an HG fix on it.
When you say swapped the "switch" is this just the knob on top that you use to turn the dial? Does the dials turn to position 1,2,3,4 and do you get any air at any speeds?
If you dont get air at speeds 1 and 2 its most likely your heater resistor pack is gone. If you dont get hot air on 4, then get the garage to clean out the pipes and check the "bodged" HG job they did.
If the resistor pack fails completely the fan will always still operate on position 4 - full speed.
Does the cigarette lighter work? It shares the same relay and fuse as the fan for it's 12 volt supply.
Check Fuse 7 (20 amp) in the engine bay fusebox, Fuse 18 (10 amp) in the drivers fusebox, this provides power for the relay or the relay itself which is located behind the glovebox and is a sod to get to!
The fan motor can fail but it is rarely the fault.
I've got the same kind of problem. My heater dosn't work on 1&2 3 & 4 work though. Also the heater rod has like sezied up and wont change from heat to cold
hmm thats kinda strange. rather than start a new thread i thought id use this one as i have no fan on speeds 1 and 2, just 3 and 4. cigarette lighter still works though
Cheers i'll check it out tonight n get one from him if thats what it is.
