A/c Problem
I did some research on Ford's 1992 Ranger A/C and research said that, to charge the A/C in the Ranger would cost about $300 + dollars. I turn my air conditioning on while driving down hill and it's pretty cool. When I reach the bottom of the hill, it remains cool for about 5 minutes and then blows out warm air. When driving back up the hill, it puts out cold air again. What's going on? Is it really going to cost $300 to fix my air? Or is there something I can do to fix this problem?

If your system hasn't been updated to the newer R-134a type, then you have the older R-12 type of system, and those cost more to have evacuated and re-charged, which is probably what it needs.
You might also consider having the system upgraded to an R-134a type, there are inexpensive kits for this, but you still need to take it somewhere first to have it discharged properly before the upgrade. The benefit, of course, is that you can then re-charge the system yourself whenever it needs it with those inexpensive cans of refrigerant you see on the shelf at every autparts store.

The first thing to do is to hook up a gauge set and see what the pressures are. Hopefully the problem can be replicated without driving; those pressures and whether the compressor is running or not will be of most value. This will help determine if the charge is the problem, or if something else is wrong. Usually a low charge results in poor cooling regardless of hills, etc. From what you describe, I'm not yet convinced it's a charge problem.
