Hey guys i need help, my a/c does not work. I recharged it myself with the truck started and the a/c on full blast like i usually do. once it was full the compressor clutch started staying on all the time, it stopped turning on and off. it still wont blow cold air, i checked all the hvac fuses and they are good. please help me its hot here in nebraska. thank you.

 

all i gotta say is GO BIG RED !!! i am the only one in my family (both sides) not born in nebraska(had to settel for kansas).did your recharge kit have a pressure guage on it? somewhere in the ballpark of 50-55psi theres a high pressure switch that will flip and it will shut down the compressor.id get a guage and see if you didnt overfill it to begin with. i put 2 cans in my truck about 2 weeks ago and at first it wasnt blowing cold air but i work outside so im used to it and i drive with the windows down anyway and i had it on today (it was raining) and it was blowing a lot colder. but a few days after i filled it i checked it and it read 50 psi. (right after i filled it it read 45-47) so i held the valve open and let some out.

 

Did you pull a vacum first? Because moisture in the A/C system is it's enemy and the only way to remove the moisture from the A/C system is to pull a vacum. If your system was discharged and open to the atomsphere at all you need to pull a vacum. (29 inches of vacum for at least 20 to 30 min) Did you replace your receiver/dryer? The receiver/dryer (also called the accumilator)will remove trace amounts of moisture but is not a substitute for removing all the moisture in the system prior to charging.

 

Highly irresponsible!

 

i know it wasnt the smartest thing to do but i had to get some out somehow.
