F250 Fan heater won't work ?
 

Hi,

I have a F250 2005 6.0L Diesel 158000km.
The fan heater stop working at any position (1-4).
Any ideas ? Where should I look ?

Thanks !

I would start w/ the fuse.

Already try that, but that's not it.

Thanks !

EATC or manual?

There is a blower motor relay in the battery junction box.

Automatic transmission.

Where is this relay ?

Sorry,I was asking EATC (electronic automatic temp.control) or manual

the relay is in the battery junction box
Same place you checked your fuse. (1.2)

IIRC the relay on the top row,2nd from left.
Double check your owners manual.(if you have one)

Thanks !

I'll try that and let you know...

Check the fuse and relay.... but it's not it...

Any ideas ?

Could it be the fan clutch ?

Check for voltage at the fan motor.
Motor could be bad.
