Air Con strangeness
Hi all,
I've had my air con re-gassed lately but it's still just not as good as it should be. I'm certain the driver and passenger side air is coming out at different temperatures with it colder on the drivers (RHD) side. When looking at the figures, the refrigerant pressure seems ok and varies with cooling requirements. The pressure sensor and temperature sensor figures don't change....does that look correct at -1bar and -10.20 deg? Seems odd. I should also mention I have a mean air con whine with rpm....definitely only when the compressor is running. Does not appear to be the clutch as we have removed the belt and the pulley feels nice and smooth with no play. |

How do you have the stratified air dials set on the dash's center vent? Are you familiar with the stratified air dials and how to utilize it? Only asking because I didn't see anything mentioned to discount its setting for the reason for warmer/cooler air temp coming from the dash vents (which the stratified air dial controls).

Get a pencil style thermometer and verify vent temps. An inadequate (low) Freon charge will cause temp variation between L and R vents, common symptom.

If the air con compressor isnt running, the left side puts out warmer air than the right as well. I've been playing with each side and the ambient air is always warmer on the left. I've done the doors calibration in ISTA/D but wondering if there is anything else I can try. |
