Overcharged A/C on my Ram 2500

My A/C was working fine in my 2007 Dodge Ram 6.7 diesel, except it was blowing not as cold as it used to. I put a small can to recharge it and the air starting coming out colder immediately. I left the truck running for like 5 minutes, took off the can and then turned off truck. 10 minutes later went to start truck and the a/c was blowing hot air and i noticed a smell of Freon and saw residue under the truck on the front passenger side shock absorber. Compressor has never started after that, i did a vacuum and a recharge but still wont work. Pressures are okay, but Freon seems not to be getting in. Help. thank you

Bypass the pressure switch with a wire and see if the compressor kicks in. What are your pressures? Ambient temp? An over-charge should not lock up the compressor. It is a closed system so you definetly have a leak somewhere. use soapy water around joints looking for bubbles.

sounds like the a/c system is low on refrigerant. At about a half pound low the drivers side still cools good but the passenger side will not

SOURCE: 2006 dodge ram diesel a/c quit comprssor clutch

I have the same truck with the same exact problem. Mine also stopped blowing while pulling a camper and indeed it is the clutch on the A/C. I was told if you can find someone in your area that can actually rebuild the compressor and not put a new one in you can come out alot cheaper! Also if you crank your truck and turn the A/C on look under the truck on the passenger side at the compressor and take a tool of small hammer and tap the compressor in the middle and it should come on and run the a/c for a little while! I did this until it finally went out and it worked! Might buy you some time!

SOURCE: Air Conditioner works intermittently

It could be your low pressure cycle switch is going bad. Check the connection to the switch and it's is located on the A/C Accumulator. The other thing to check is the A/C relay and that is located in the glove box. There is a panel in the glove box that say's relay, there is three relays in there and one of the out side relay's out of the three is the A/C. can not remember which one it is. The middle relay is the fuel pump and the other one is the third break light. Switch the two out side relays and see if your A/C get's better. the other thing too is if the R134a is just a little low, and needs to be topped off. Good luck and hope this helps. if your going to try to recharge the A/C system your self, keep in mind not to over charge.

My 2003 dodge 2500 has air condition issues.at idle it blows cold air as long as it sitting still.as soon as I start down the road and drive a few miles the air stops blowing cold.HELP


On a vehicle 11 years old, I would say
put gauges on it & then leak test it.
Most likely has a leak & is low on refrigerant
& when you move ,you put too many BTU's across
the evaporator from the cabin & it is not at 40 degress
to remove the heat

I have a 2006 Ram 2500 Diesel. My heater quit working. One minute it was blowing hot air, then next it was blowing cold air. Any ideas what this is or how to find out without spending an arm and a leg?


low coolant. disconnected or faulty servo to control difference between hot and cold or the heater core could be clogged. if it warms up when reving the engine then it is probably low coolant.

No a/c, no freon....2001 dodge ram 2500 diesel 2 wheel drive


It is most likely the evaporator leaking. You'll need to remove the dash panel assembly and the heater housing to gain access. I have replace many Chrysler evaporators in trucks, minivans, and Jeeps to name a few. I hope this helps.

Transmission- 2001 Dodge ram 2500 diesel 4X4


I have a 2002 Dodge Ram that doesn't like to shift into 2nd when flooring it from a Stop. Imagine if you were to floor the gas in neutral, the engine REDLINEs and the engine governor kicks in to keep the RPM from blowing the engine......while stuck in first Gear. If i let off the gas, it goes into 2nd fine. I have replaced the Speed Sensor on the transmission ($18) and it seemed to fix it for one day. After 200 miles, its doing it again. ANybody have legitimate answers in here? Its only got 60K miles..wtf?
