About a year ago before winter hit I went to turn on my defrosters to defog my windshield and when I turned it on I got no heat, but the fan still blew, though got a little burning smell for a bit, and I could hear the AC compressor engaging and disengaging in about 5 second cycles. Each time it did my oil pressure would suddenly drop and the car would lurch and the RPMs would drop. This also seemed to cause the AC to stop working as well, the fans only blowing ambient temperature air.
I went that winter with no heat and left it alone. However, hoping to avoid this again, I tried turning on the AC and the Heat. I get fans blowing, and I can hear the AC compressor cycling at idle, but no pressure drops or RPM loss anymore. When driving I don't notice the cycling, though this could be cause I can't hear it, but still no heat or cool air.
Any ideas?
