AC Issues - Compressor Clutch Always Spinning or hidden from view?

[tonynf89]

Hello,

I have a 2007 Toyota Yaris and live in Canada. With the warm weather finally returning I went to use my AC on the weekend and it only blew warm air.

Today after work I tried it in the driveway and it started cold, but as soon as I took it for a drive it warmed up again.

The car has not cooled down yet so I have not seen if it will consistently start cold and warm up or if this was a one-off event.

I tried attaching a A/C Pro refill kit to it, but when I attached the pressure line to the low side (with Max AC on) the gauge was red. This indicates to me that the compressor is not engaging but when I look at it, the pulley is spinning and the wheel beside is also spinning (see image below). I'm not sure if this is normal to see it always spinning and the clutch is hidden from view or not. When I try spinning the wheel beside the pulley by hand with the engine off it does not budge.

I have also tried disconnecting the connector at the front of the compressor with the engine running and set to max ac and it lowered the revs of the engine, and when I connected it back in the revs went up.
