Well this all started yesterday, a very hot day too. So I leave for a drive, turn a/c off after startup, I open windows and roof and go for a drive. I get into heavy traffic and I got no breeze so I close the windows and roof and turn on the a/c. All I get is hot air coming out, doesn't matter what mode, temp setting or fan setting only could get hot air. Now I notice the oil pressure sitting 2 marks to the left of center when idling and it goes 1 mark to the right of center during acceleration. I never noticed this before I always thought the needle stayed at center. Maybe not related to a/c. So I turn it off again and run some errands and come back and start it up, same thing, hot air only and nothing else. I got home and let it sit for a couple hours and go start it up, everything is fine, full temp control cold or hot any vent any fan speed. I go for another drive today and it doesn't seam right again, now the odd thing, when I shut the engine off, removed the key and opened the door to kill the radio, THE FAN BLOWER KEPT RUNNING, excuse my language but WTF is the deal with that? I turned the key back to run position and off again and it turned off. I started it up again and drove home started to get some cool air but now the fan doesn't adjust to any speed it just stays on low speed. I been looking through some hvac issues others are experiencing but which if not all accuators may be causing the problems. Should I try pulling a fuse to reset the system?
