I'd check the power to that as it could be the fan.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi all
Heater runs ok for about 5min then fan stops working have replaced the cabin AC control and made no difference
If I switch the ignition off and re start the engine it works as normal, but only if i switch off and remove the key, it does not work by just switching the ignition on and off.
Any advice before I start looking at circuit diagram
Thanks in advance Steve
Yeah - try giving the relay a wiggle. Forgot which one it is but it's above the fusebox in the footwell. Could very likely be a dodgy connection on one of the pins.
Hi,
No it's on the drivers side footwell above the fuse box. If you find a relay diagram for there it'll tell you which one the heater fan relay is.
Think it's no.1 one in the diagram:

Think I will have to check the ballast and motor. Are these easy to get to
Steve
Just a thought. As you have to remove the key to get it work again, the accessory circuit might have an issue. IIRC it has a time out after turning the key to accessory then back to 0 in case you forget to take the key out, removing the key resets the timer for next time. Could be fuse for accessory or ignition switch fault.
