Hi guys, would apprecaite any help you may have as Im just about ready to give up on this one.
There heater will only blow cold air whilst operating and the climate control electrics operate normally as they have in the past.
What I have checked :
- Checked the Heator core and there are no blockages
- Checked water pressure at inlet and outlet of heater core whilst revving the engine.
- Checked the tap on the inlet to the heater core, checked OK.
- Checked the climate control for error messages and none were displayed.
- Engine temperature up to spec as I think the blower water temperature is (hand test on blower hoses).
For the life of me, I cannot understand why there is no hot air when the fan is operating normally. Unless someone can tell me that there is a bypass alongside the heater core or something like that, I cannot understand why this bugger dont work.
I am a electronics technican if that helps and have had previous experience with blower motors failing and blocked heater cores etc, but nothing like this crap.
