VE SV6 Series II
hey guys, I’ve got a ve series 2 sv6, I’ve akways had issues with th aircon, on a hot day, at idle or low speed it’s completely useless. Most the time I drive with windows down as the aircon doesn’t do anything unless im on the highway

I’ve taken it Holden, to a mechanic, to an car aircon guy and finally to an auto electrician. All of them said “it’s working”

I’ve finally had enough, today I popped the hood to check the visuals, I noticed the radiator fans turned on for 10 secs, off for 5, on for 10 and kept repeating. Is this normal with the VE? I thought the fans stay on continually if the aircon is on. How can I diagnosis this further?

Fans will activate when the ac system hits a certain pressure then shut off when it gets below a certain pressure. Cycling is normal.

It's either low on gas or the compressor is failing. Any decent ac tech can check that pressures are in range and diag either gas or compressor. At idle vent temps should be around 5 deg.
