I have found a vacuum leak in the blue vacuum circuit and have traced it to the front seats. Why is there vacuum going to the front seats of this car? i have traced a vacuum leak to the drivers seat. Do they need to be hooked up for any reason. How does the vacuum switch work in this circuit? Can it affect the A/C causing it to blow HOT air?

Thanks in advance, Moose

The vacuum goes to the seat back tilt mechanism. Yes, it can cause other vacuum problems, but I'll bet the hot air is caused by a faulty mono-heat valve.
