Why is my 2001 Jag XK8 inside air hotter than outside air after car driven several miles?
The inside air flow gets hotter than the actual outside air temp after the car is driven about 20 miles then shut off for several minutes then driven again. If I select the inside air function the air out of the climate control gets a little cooler. If I turn on the air condition everything cools down and stays that way until I shut it off for a while then the outside air fow starts to get hotter after several minutes.
I suspect that the condenser coils, inside the climate control box under the dash, are getting hot due to the condenser cooling hose lines inside the motor cabin transferring motor heat to these hoses and making the coils hot. As the outside air blows in, these coils transfer their heat to the outside air causing the cabin air to get hotter than the actual outside air. I do not know if my theory is right about this. Does anybody else have any ideas about this problem? Is there a possible fix for this? I did check the problem of the plastic gap that leads to the input air duct and corrected that already but no help with this problem.
