Drove our truck on a 200 mile trip through the mountains this weekend and everything worked PERFECTLY except for the last 10 miles when we noticed that the cabin was warming up and the A/C was on but not coming from the upper vents. It was coming from the defrost vents and maybe the floor vents. I got home and checked for vacuum leaks(there were none), and checked the operation of the vacuum pump and found that it was not turning on, so I disconnected the electrical connection to the pump which showed 12+ volts on the multimeter, plugged it back in and it worked again. I cleaned the connection with electrical contact cleaner and reconnected it and everything seems fine again.. weird.
99' PSD extended cab, long bed, 4x4, 6 speed. 4" custom built exhaust system with MBRP downpipe. EBPV disconnected. Southbend Organic clutch/solid flywheel. Goodyear Wranglers.
