1st a/c thread of the year! 98v70
here is the rundown, So the problem is, a/c only kicks on when i jump the power to the compressor? any one ever have this happen before?
- i read i only have a low fill by pass front light
- i jumped the sensor by the pass side firewall no change in system funstion, im told thats a low pressure sensor
- freon pressure is high
- when i jump the + wire at the comp, comp turns on, a/c blows cold
- is the other sensor on the a/c line by the headlight a high pressure sensor?
trying to get a/c before all the real heat! THANX IN ADVANCE!

thanx so much. the system worked last year fine. though this year it did not. it is overcharged, as i found out this year. so i thought it odd that it worked then and not now. the previous owner apparently overcharged it, so ill use the machine a purge some out and see what happens. THanx again for the info.

so...here is the update. vaced and charged to proper pressure. Still no a/c. what i found is that there is no current going to the compressor. what turn the comp on? where does that signal come from? Any chance i could get wiring diagrams? Checking a relay was also suggested? does that exist. thanx for the help. And i did no replace low the high pressure switch yet. wanted to rule out cheaper options first.
