driven home from work in my P38 I parked it in direct sunlight so I had a little play around with the Air-con in the old bus..
I've been operating under the assumption that it didn't work, mostly due to the feeble blower output...
Anyway I turned the aircon on and the if the hieroglyphs on my HVAC are to be believed it was set to "low" the air coming out the dash seemed to be very cool, definitely colder than the ambient air outside, however upon inspection the clutch on the compressor isn't spinning with the pump when the air-con is engaged.
HOWEVER whenever I put the A/C on the engine note changes and she seems to bog down slightly, exactly what would happen when the clutch engages, however I can't see it doing much..
She does have the notebook on the HVAC panel, I've read some place that if the HVAC is in a fault condition it won't allow the compressor to operate?
BUT surely the engine wouldn't change note if nowt was happening??
Any ideas gents?
