Well, I may be wrong. I went to the parts link on here to see if the 95 and 98 use the same part number for the evap temp sensor. For the 95, it does not list an evap temp sensor. Opps. Sorry about that.

It does list temp sensors, though. The one on the receiver tells the aux fan to start. Not likely that one. But it also lists one for the engine block. Apparently, if the block goes higher than 130C, it shuts down the compressor. That sensor might be bad, or disconnected.

For RTDs (resistive temp detectors), the resistance goes up as the temp goes up. So if it's unplugged, the computer thinks the engine temp is high, so it shuts down the compressor. Also, if the element inside an RTD breaks, it thinks the temp is very high. If you can locate it, see if it's unplugged. If it's not unplugged, unplug it and measure it's resistance with an ohm meter. If it indicated infinity, it's bad. Make sure you're working on the right sensor, though.
