If it cools going down the road, but warms up at idle, then the cooling fans re not working correctly. This will make the high side pressures run to high, and the ac compressor will be turned off till the high pressures drop. When you are driving down the road, the air running across the condenser will cool it down so the pressure drops to normal range.

The best way to test this, is to place a fan in front of the car so it is blowing towards the radiator from in front of the bumper. Turn the ac on and see if it will blow cold air out the vents. If it does, then you need to check why the fans are not working correctly.

Your answers were clear and the diagrams were perfect. Dealer wanted $87 for an hour of labor and even I did it in 15 minutes.

EdUSA

HONDA PLATINUM was great. I really appreciate his help. I was ready to trade my new Honda until he told me to wait until I got 3,000 miles on it and my gas mileage would get much better.

SummerUSA

I took the Power Steering O-Ring service bulletin linked from JustAnswer to my Acura dealer, and not only did they no-charge the o-ring, they also replaced the power steering pump at no cost.

Gary RStevenson Ranch, CA
