2003 Mini Cooper!!

Current Symptoms.
1. Light on A/c Switch on solid (no blinking)
2. Yes, I can hear the compressor turning on/off
3. Low speed fan does not turn on when A/c is turned on.
4. When I attempt to recharge the R123a i get half way and the high pressure dump valve on the compressor opens.

A/c stopped working by dumping the refrigerant out the port on the bottom. During troubleshooting I found out the my low speed resistor was shot. Replaced!! I tested afterwards by jumpering the battery to the connector pins and fan worked in both speeds. I recharged with more r123A but didn't get halfway through the can and it dumped again. I noticed that the fan wasn't operating.

Since I replaced the fan resistor I expected the fan to turn on when the A/c is ON, correct??

I don't want to waste another can of r123a.....should I recharge or will it dump again?

Should the fan be ON with the A/C on?
What else should I do?


Thanks
Doug
