Okay started but not cool
Expert:  Tim Mohr replied 2 years ago.
ok, then you are either low on freon, or out of freon, it will need to be evacuated and recharged,Tim
Customer: replied 2 years ago.
But clutch engaged but fans not on
Expert:  Tim Mohr replied 2 years ago.
the fan wont come on until there is enough freon to bring the high side pressue up,Tim
Customer: replied 2 years ago.
Ok I have a set of pro series gauges when fans kick in they go to 40 low and 200 high then when fans stop high side jumps way up
Expert:  Tim Mohr replied 2 years ago.
if the low is 45 and the high is 200, then the air should be cool, until the high side goes way up??
Customer: replied 2 years ago.
Yes air is cool but when fans disengage high side shoots up then before it hits 350 fans will engage again
Customer: replied 2 years ago.
And I still have to leave jumper in
Customer: replied 2 years ago.
