Good observation on that little bit of dragging. Cold outside. Use the front window defrost? The AC always runs when the vent setting is in front window defrost mode. This is true for most if not all cars.

Just unplug the electrical connector on the drier.

Hi,

I believe only one wire is attached to ac compressor and it is unhooked by twisting the connector. AC units in some vehicles run all year round, so the fact that it is cool out does not stop it from running.

You can see if it is running by looking at the AC pulley. If the front plate on the pulley is spinning, the clutch is engaged. If the clutch is unable to disconnect, then the clutch is frozen and the fan belt should be removed until you are able to repair it.

Dear Horatio,

Hope you're well. I'm not an air-conditioning expert: far from it.

If the compressor is operating, the compressor pulley's faceplate turns rapidly, because the clutch is engaged. If compressor pulley's faceplate is not turning - even though the belt turns the pulley itself - then the clutch is not engaged and the compressor is not working.

At the risk of laboring the obvious, make sure the right-hand button on the control unit is "out", i.e., is not flush with the control unit's front surface. The '95 940 climate control unit is set-up differently from those used on earlier models.

On the '95, pushing the "snowflake" button (on the right, as you face the control unit) - so that the button's face is flush with the control unit's front surface - means that the air conditioning is "on". On earlier models, when the right-hand button is flush with the control unit's front surface, the air conditioning is "off". The earlier arrangement was counter-intuitive: generally, to activate a device, a button is pressed, not "released".

I seem to recall a post, suggesting that disconnecting the wiring harness to the low-pressure cut-off at the accumulator, will cut power to the compressor. The accumulator is an aluminum "can", with refrigerant pipes running to/from. It is on the left (passenger) side of the engine bay (North American models), near the firewall. I do not know if cutting the power supply to the low-pressure cut-off will have other impacts.

Perhaps one of the Board's air-conditioning experts can confirm or correct my suggestions.

Hope this helps.

Yours faithfully,

Spook
