2001 Jaguar S Type 4.0 V-8 No heat or cold air... Seems to just blow ambient air temperature regardless of the setting. I have flushed and re-filled the coolant. I have attempted to charge the A/C system with R134a, but the system doesn't seem to want to take any. When I connect the can, it feels like a small amount of refrigerant enters the system and the compressor kicks on, but then nothing more. It doesn't seem to matter if the a/c is on or off.... still same performance. I have checked the lines going into and coming out of the firewall and when the car is at normal running temperature, all lines are hot to the touch (if you can stand to touch them). Any ideas on what the problem may be?
The common prob is caused by the wiring to the dual control valve corroded/oc behind the front bumper liner. the centre of the 3 wires going to it are favorite and should have battery voltage going to the centre wire check that using a load ie.a 21watt bulb bet its missing if so remove bumper liner untape the wiring and find o/c and repair or rewire the power from the underbonnet fuse box just above

um...strange ...engine temp reaches 210 before thermostat opens and lets water circulate ..fans go on before that normally..180 or so..hot air from heater going to cold air? strange...could you elaborate for me /us?

Other than Freon and compressor
there are other causes related to car AC not blowing hot air. It is also common
that the radiator or the condenser is clogged up with bugs, dust and dirt, or
road debris and trash. Get it cleaned. Hope it helps. Also if you think your
car air conditioning is not blowing cold enough the first step is to check the
output temperature at the center duct with a thermometer. Make sure the
recirculation or max air mode is selected and the blower is on low speed. 40 -
50 degrees is perfect. On hot humid days here in south Florida 55 degrees is
welcomed. Step 2 is to have a professional connect a manifold gauge set and get
some high and low side pressure readings. With these readings a logical path of
diagnosis can get your AC blowing cold as it should be.
