Not having a thermometer to check the vent temperatures??? So weird !

Any thoughts?


Appears??? Turn on the engine and AC, visually determine if the CENTER part of the AC compressor is turning, not just the outer pulley.

Re: AC Compressor not kicking on when trying to recharge system

With today's Phx temperatures, I would hope for lower, but maybe that's what a Nissan Maxima can deliver. Of course it's only about 85F here today outside, so will get 30F higher in summer. My 1998 and 2004 Nissan Frontiers have great AC, and those have their condenser/radiator cooled by a fan clutc...

It's good that you actually did not add any refrigerant. Because unless you just omitted that step from your post, you need to evacuate the system.

That's what I mean with "visual inspection". If there's refrigeration oil getting out, so is refrigerant.

A leak. Oftentimes a combination of visual inspection, UV dye, electronic sniffer, and soap bubbles must be used to find a leak.

Re: Ac is not getting cold when ilde

Can you provide both high and low AC pressures at about 2000 rpm? And are all the electric fans in the engine compartment spinning when the AC is on?
