I would - the low side should cycle between 20-40 and the high from 200-275 -
I also read on here that the sight glass should show light bubbling - no bubbles and it's either way overcharged or undercharged, and lots of bubbles mean it's slightly overcharged...
I've got an even stranger problem where my fan (there's just the 1 on the car, no 2nd one for A/C!) only comes on when the pressure builds up enough to kick the cutout switch - it should be coming on when the A/C is running to keep the temperature drop and keep it from overpresuring, so rather than find out what is wrong I am going to just put a switch on the fan so I can turn it on manually when I'm running the A/C in the city (on the highway it gets enough forced air that it actually works correctly...)
Anyone else have this sort of fan problem chime in before I start modifying mine!!!
