    LBZ: I can get the ac system to work if I put water over the condenser

    The ambient temp is 85. I had the system vacuumed and recharged. All pressure levels read right where they should be. No it doesn't not work driving down the road unless I wet the condenser first the drive it will last about 30 mins.

    LBZ: I can get the ac system to work if I put water over the condenser

    Well I have checked everything in the ac system. Changed out switches high low ambient temp switch. System only comes on if it is cold outside around 65 or below or it will come on if I put water over the condenser. The truck temp and trams temp is all normal.

    LBZ: I can get the ac system to work if I put water over the condenser

    What does this mean? I sprayed water over the condenser to help flush and then the ac came on for about 20mins. Then it shut off unless I put more water over it. Help please?

    I know what you mean now! I have washed them with water and sprayed compressed air at them. They don't look that dirty. But what is the best way to clean them?

    LBZ: Ac only works when it's below 70 outside?????

    I have a 07 Silverado with 150k. I have done everything to try and fix the ac. I had the system vacuumed and recharge holds pressure and correct levels. I have changed out all switches low high and ambient temp. I can't get the ac to work when it's above 70 outside. Does anyone have any ideas!?!?

    LBZ: A/c only works when it rains out help?????

    I've been doing some research and a lot of forums are saying that the second sensor behind the passenger marker light is for the temp to be displayed on the hvac module. Mine is a manual set temp the sliding type mines not the automatic type. Does this make and difference?

    What is the second sensor for? Does it allows the hvac system to recognize the temp and decided whether or not the compressor enages?

    LBZ: A/c only works when it rains out help?????

    Just tried soaking the sensor and got nothing. I'm going to wait till tomorrow and check the wiring futher. Are there anyways to check to see if the sensor is working properly? Or should I just replace it? Using a volt meter what should I be reading for volts when I see if power is being sent to it?

    LBZ: A/c only works when it rains out help?????

    I know the problem is weird. It took me weeks to figure out that it only worked when it rains outside and also it worked once when I when threw a car wash but stopped working after a little cruise and it dried up. The system is charge properly and you can jump the system and all works perfect...
