heater problems
hi,can anyone solve my heater problem? 1994 xj40 heater blows hot in footwell but cold at dash level & also at demist, i have checked the upper blend motor but this appears to be working, could the actual blend flap be stuck & how could i remedy this or do you have any other possibilities as to what might be causing this?

I'm not well versed on the Jaguar heating system, (totally ignorant as a matter of fact), but it seems to me that if the heater core was clogged you wouldn't be getting heat anywhere.
From your description, I would go with your initial diagnosis - that it is a routing problem or blockage rather than a complete lack of heat.

I actually had this problem a few weeks ago and it turned out that the left demist flap broke and fell into the upper rotary flap. The flap would turn a little back and forth but not enough to allow heat to get to the upper part of the system.
I pulled the center vent, instpack and passenger veneer panel to get to the center vent vacuum flap fasteners and removed it for access to the broken demister flap. I pulled the broken part out and the rotary flap operated thoughout the proper range.
