Hi guys, remember me? Been a while I know. Things with school became so hectic I was doing nothing but school and work until the semester was over. Now that that's done I should have time to relax. Yeah right, the first week I had to work double my normal hours, then the week after I was sick, now everything's breaking, and who knows what'll be up next week.
Anyway, some of you might remember last year I was having an intermittent A/C problem. Suddenly the air would stop blowing cold. I could not replicate the problem at home and reading the pressures always resulted in normal readings.
One day this happened on the way home and it persisted all the way there. When I got home, I checked the pressures to see what was up. Pressures were about 100 psi on the high side and >250 psi on the low side (don't know exact pressure there, I just put on the cheap gauges, and it went off the scale. Probably broke that set, tho it wasn't anything special.)
I thought it could be the compressor or the fan clutch. I thought a bad fan clutch would cause higher than normal pressure in the high side. How could pressure be so high on the low side like that, wouldn't it flow backward through the orifice tube and stabilize?
Some other reasons why I suspected the fan clutch is because it always seems to happen during the hottest parts of the day (never happens in the morning or at night), is an intermittent problem, and never happens over 85 MPH.
I tried to turn the fan the other day by hand and noticed it is unusually firm. I know it's not supposed to free-spin, but it only turns about an inch after pushing it.
Seems like everything's going to **** this summer. I'm posting this from my laptop running on a BartPE disc, because the hard drive just died. Oh, and I have to have 3 teeth filled, too.
