2003 jeep grand limited 2.7CRD heater issues

[simoncoops1]

Hi there, I have already included this in a 'various' thread but it's causing such an issue that it warrants its own spot. I'm hoping someone can help.

Right, I started with no heat/or cold coming from my vents. Blend doors.... Changed them.
The doors were confirmed snapped but now work with the temp knobs (dual zone).
The heater (hi/low knob) has always made the 'noise' of a blower (increasing and decreasing with the knob) but now airflow.

So.... The doors work, the 'blower noise' is there but there is no airflow!!! Argh. I'm going crazy with it.
Could the heater resistor fix this? Some miraculous fix??

Thanks

No specific knowledge of you particular car but generally speaking.

If you can hear the fan & check that it is indeed turning by looking under the scuttle by the wipers then, you would have to say something internal (flaps) is closed, or has come off (trunking) either of which will be difficult (not impossible) to get to.

I was beginning to think the same thing. Anyone know of off hand of any/all access/view points for te air duct in the heater system. Could it be a blockage and or broken or sticky door.
I'm beginning to lose patience with the whole thing.
