Is this a clutch problem, a switch problem or is the compressor still bad? Is it something I haven't thought of? The truck has 110K on it, but I love it. I spend a lot of time in it every day, and would really like a break from the heat of August in Central Maryland.
Any help is appreciated, thanks.

We will all assume that you evacuated the system with a vacuum pump prior to filling with 134a. Make sure that that your wire connections to the switches are connected and not loose, espescially the one on the accumulator. If all is o.k. I'd do what BlazerLT says and probably add a little more 134a.
