Ok...have a 2011 E350 5.4L 15 pass. van with 69,000 miles in the shop. A/C is just too damn warm at idle. After 3 compressors, accumulator, 3 orifice tubes and rear expansion valve I need someone to tell me WTF is going on? System calls for 3.38 lbs...so I have done that. At idle with front and rear blowers on high the low side pressure is 60 psi and the high side is 240 psi. Turn rear unit off and front blower on low and low side pressure drops to 40 psi, high side reads 250 psi. Under acceleration the low side comes down to 35 psi and the air blows cooler. Now I have NEVER seen anything like this other than problems with the items I've already replaced.

 

You know how when most of these forums have ZERO solutions to the actual problem and you're left thinking WTF are they talking about? Guess I could just start talking about my grandmothers hip issue now before anyone actually comments on my A/C problem. LMMFAO!!!!!

 

Can you squeeze an electric fan between the grill and condenser? Can you get a fan clutch with a lower engagement temperature?

OR you could have done just a teeny tiny bit of looking here on FTE long enough to realize there's a forum dedicated to A/C issues!! LMMFAO or whatever you meant to type huh? Cooling, Heating, Ventilation & A/C - Ford Truck Enthusiasts Forums

Believe it or not the lack of response here is the better course since anything contributed that doesn't meet your needs or expectations isn't helpful at all----is it preferable to receive guesses or wrong info instead?

Then again most competent mechanics even of the DIY variety understand and/or know most A/C system issues are NOT particular to a certain vehicle, that the solution or most likely to work solution is related to the refrigeration cycle itself.

Yeah I know the feeling of WTF---as when someone goes off without doing a bit on their own first??
