Re: 2004 F150 clutch not engaging
A/C clutch will not engage. I can jump with a paper clip at A/C clutch relay and clutch engages and A/C blows cold air. You are likely low on refrigerant or your pressure switch is bad. Do not simply jumper the switch and run the unit, except for the test that you did, can damage the system because...

Re: Car AC blowing warm at high Demand
Compressor "off" pressures do not tell much. I see where with compressor engaged, and at high engine rpm, that your highest pressure is 200 psi. I'm in hot Arizona, and all my R134a vehicles typically measure 250-275 psi on the high side. Feel your lines going into and leaving the firewall...

Re: Car AC blowing warm at high Demand
When parked in the sun, remember that seats, dashboard, interior can be alike 140F or more, takes like 15 minutes until the cooling really sets in. Start out with outside air (vent) in because that hot air is COOLER than the interior's air; later switch to recirculate mode.

Re: Car AC blowing warm at high Demand
You were over 100 grams R134a low when it was re-filled. I wonder if you have leaked refrigerant since then.
Also make sure all your cooling fans are operational.

Re: High Pressure Mystery
Wow. several weeks to track this down, when a test can be made with a sheet of paper......
Anyway, good find.

Re: High Pressure Mystery
After you spray the condenser with a hose and find that the high side drops like a rock, check to see if the fans are turning in the proper rotation. Also see if there is air flow going thru the condenser and radiator. Definitely appears to be a condenser air flow problem. This would not be the fir...

Re: High Pressure Mystery
Have you tried this? bohica2xo knows his stuff, but cannot be there hands-on, so at least try this and report back to him.bohica2xo wrote:400 psi is a condenser issue. HEAT is not being removed.
Spray the condenser with water & watch the high side pressure.

Typical. More air forced through condenser, higher rpm.ZOOOOMZ wrote:I did drive it today, and was pleasantly surprised that it performed even better on the road in actual driving than it did in driveway tweaking!

Drive it a few weeks, see how it works. If OK, STOP.

Re: High Pressure Mystery
Is that a serpentine type of condenser? Those are more likely amenable to reverse flushing than the parallel flow condensers, where solvent can bypass many passages. That's why parallel condensers are most often just replaced with new.
