The aircon did not work. TestBook gave an Evaporator Sensor Fault and Heater Sensor Fault. TestBook could clear the Heater Temp Fault. Fitted new Evaporator and Heater sensors and same result on TestBook (unable to clear Evaporator Fault) Prior to this we had the car de-gassed (it was full) we changed the Drier Unit and both switches. Had the car re-gassed.
TestBook can Force the Compressor On result cold in the cabin (clutch OK). But no indication of a Grant A/C On so next is fish out the HeVAC and get the AVO on it? Incidentally The air/con will very, very occasionally work but only on a very hot day (havent seen any lately) and not very well and not for very long. Book symbol comes on after five Min's or so.
Well got the old HeVac out and poped in another I thought was a good one (same numbers 1998, mine is a 2000 car?) Air/con works! BUT the book symbol came straight on with left hand blend door fault that will not be cleared on TestBook Arhhhhhh. Put old HeVac on and blend motor works fine and travels correctly through Cold/Warm/Hot but no Air/Con and old message Evap sensor again. Put back replacement HeVAC and same Fault on Blend Motor at 119%.. I have been through the procedures for new ECU and reset and tried forcing it to no avail. Bugger.
So took the original HeVac apart and substituted its motherboard with the new unit and poped it into the car - so new switch part and old motherboard result no book symbol and everything working as it should - Result.
Many thanks for those members why helped with ideas.
