Ive had my truck around 5 months and the heater has always worked but every now and again it stopps and a couple of minutes later it starts working again, until i went to turn it on one day and it just doesnt work ! I need to get it sorted asap so any ideas or clues would be great !!
Im thinking it could be the motor, if so where is the motor situated and is it hard to get to ??
Many thanks

 

could be the blower motor resister

 

check the harness going to the blower motor on far pass side.
mine dried up and corrodided on me...but no blower motor is not hard to do.

on the outside of the blower motor housing you will see a notation that says
cut here
just follow that outline and you will be fine.
might need to remove the pcm to pull the motor though...i did.
disconnect batt if you do.

 

Thanks for replys, Im going to get a new motor and try that !! Hope it works cos its a bit cold at 5am on a morning going to work. :/
