Put gauge and can of freon on was just in the edge of blue area so I added so freon then the clutch didn't seem like it was kicking on then the gauge went to the red area any ideas what I might be able to do .Have a seven hour trip back to northwest Ohio Monday mourning

you added some refrigerant and it then the low side fitting was making bubbles that would be a bad valve leak. with the charging gauge on the low side and the compressor shuts down the gauge will go up to 100PSI RED zone. when compressor runs then it should drop down to the 20-45PSI area. AIR TEMP @80 deg F low side 40 psi / high side 225PSI. doors windows open ac fan on max. leak additives can block the flow. orifice gets plugged up. if its other than a charging problem best have ac shop look at it.
