My question is: I have a 99 dodge Ram 1500 4x4 Sport, 360. I am having problems with my A/C system. I turn on my A/C and the com. kicks on and off. So i tried to put some coolant in it but it want take it. So i bought a accumlator and orffic tube. I put on the accumlator but i looked for the orffic tube but couldnt find it and i dont know where else to look unles it is under the dash or i over looked it. Well i hooked eveything back up and tried to pull a vacum but it wouldnt do, I tried to add coolant but it wouldnt take, I tried another and it took but i dont know where it went and try to put another in and it want take it. I dont know what to do besides taking it somewhere, cause i have done all i can think of doing. If anyone can help let me know.
