what do you mean "it would not take a charge" -- you may have to jump the low refidg. sw. if this is indeed the reason that the compressor is not engaging -- others here will know better than I, what you should do (LarryBible?)
I would def. take pressure readings (with the car on and the ACC set at max cool) and post them
See this post for correct pressures:

You should be charging the system on the low side (and I would be using a R134 with UV dye)
