I've been having problems with my AC for the last few weeks, it pumps out warm/cool air, not COLD Air as it should.
Its going in to the dealer tomorrow.
But I have noticed one thing over the last few days, if I am stationary for a few minutes with the AC on, every 20-30seconds the rev needle drops a bit, picks up a bit and then back to original position. When this happens you can feel the car slightly shake.
If the AC is off, it doesnt do this.
I videoed the Rev needle today to show the dealer, as I guess they may just say "we cant find any fault"
Not sure if this is related to the AC problem I've been having.
Anyone else had similar issues with AC? or with the fluctuating Rev?
