well I didnt vaccum the system down I went ahead and added freon If you didn't pull a vacuum before charging, there's air in the system and it won't work correctly.

The ac started blowing cold driving in the highway and stop when idling .. I'm never mess with ac just what I read or seen and taking advice from shade tree mechanic.. I pour the oil out of the old compressor and rubbed between my fingers it felt smooth.. I may go ahead and flush the lines and evaporate and condenser.. Does that have an auxiliary electric fan right behind the radiator? If it does I would check to see if it's working. Probably has a small transistor type relay that's probably bad. If it's cooling going down the road but stops when sitting still it doesn't have enough air flow across the condenser. It is still a good idea to have the system evacuated before recharging. Moisture in the air can cause problems down the road.

It's called a relay but doesn't look like a traditional relay. I'm not sure exactly where it is on a Dakota but I normally find them bolted to the core support or frame rail behind the bumper, fascia, or headlight.

The system will come on and go off while using the AC, supposed to do that. But, if it does it in quick succession, on, off, on, off...that's short cycling. Usually a sign of not enough freon. These systems do not hold much, so getting in the correct amount is very important.You need to start from scratch.... make sure everything is flushed. You may not be able to fluch the condensor, most newer models you cannot. If the clutch is all that was bad, everything should work like it did. Make sure you are getting power to the clutch. What are the pressures? Low side should be around 30psi, high side (depending on ambient temp) around 150-200. But, you gotta get all the air out by evacuating the system. You probably need to take it to a shop that has the correct AC equipment. Hope this helps! Jeff
