    AC increases temp while sitting idle, blows 60F while driving

    I replaced the compressor last year for the same issue having today, the new compressor improved and helped maintained temps in the mid / upper 60F while in traffic but this year the heat here is TX has been very high and very early in the year. This year it would not maintain below 70F, climbs...

    AC increases temp while sitting idle, blows 60F while driving

    Hamfisted - I install my gauges while at idle ambient temp 95F , Low side 60-62PSI, High side 210-220PSI, in cabin temp 72F~. I started to hose down (not a mist, more low pressure hosing it down) the front end through the front grill. I did that for about a minute, walk around the window to see...

    AC increases temp while sitting idle, blows 60F while driving

    I can try the water hose suggestion. Do you know if the freon travels through the condenser in serial or parallel paths ?

    AC increases temp while sitting idle, blows 60F while driving

    Interesting you would bring that up. I did not put oil back in, I pumped the system out a room temp and the car should not been start for over 24 hours, so my thought was it was only Freon being pulled out not oil since is was under pressure of only 85PSI ambient temps You think I should add...

    AC increases temp while sitting idle, blows 60F while driving

    i'm think I may have a weak compressor or some restriction For restriction what the best way to test , temp probing the condenser inlet and outlet , temp probing the evaporator inlet and outlet Can the condenser be cleaned If I remove it ? Is the freon traveling through the condenser serial or...

    AC increases temp while sitting idle, blows 60F while driving

    I did vent the whole system to replace the expansion valve, I assume that means its empty and needs to fill to 34oz. That said, prior to putting in the last 6oz or so, I was monitoring the cabin temp (AC on high, AC temp set to 60F, all vents open, rear AC ON w/ same setup) The temp in the...

    AC increases temp while sitting idle, blows 60F while driving

    Several questions above: Yes I vacuumed out the system for 2 hours down to negative pressures, let the leak up for 20 mins. No leak , gauge did not move Yes I measured the freon going in, 2.5 cans of 12oz each. The truck hood says 34oz. I think I'm there , perhaps not over full This truck has a...

    AC increases temp while sitting idle, blows 60F while driving

    Replaced compressor and fan clutch last year, this year the Thermal expansion valve , but same results. Outside temp 95F , Pressures at idle low side 60 psi (pipe not cold), High side 220psi (pipe hot), at idle vent blows at 70F. I drive down the road 50-65 MPH and temps drops 58F. I pull over...
