hey guys new owner here,with alot of questions on my truck and never owned a dodge before so i need ur help, 1st off its a 1997 1500 quadcab, with a 5.2 motor,my 1st question is (keep in mind im not a mechanic) a diagram or explanation of which a/c line is the low pressure port? i need to add freon? and the 2nd question is the drivers window goes up great but coming down,it comes off the track and falls,now ive taken off the panel and see that there r 2 nubs that sit in the track to make it go up and down but theres nothing that hold the nubs in to keep em from popping out as it is lowered, is there suppose to be,or maybe my track needs to be bent closer together to keep em from coming out? tell me how to proceed and i will try it thnx in advance for any and all assistance. troy

 

Your low side pressure port is located by the drier (the black can thing on the passenger side of the engine bay) That's where you stick the a/c coupler for the refrigerant.

As far as the window, unless something is glaringly broken, you, might have to fiddle with the track to get it to stay.
