1986 Mercedes 300e The air conditioner vents blow cold out of the center two and hot out of the two sides and the defroster vent. I tried to press the lower vents button and the high setting on the climate control panel but hot still comes out the two side vents and when I slow the car down at a red light the vents shut off altogether then come back on when I speed up again.

A few hours later, it came on out of no where, and worked fine until today. It spontaenously turned off, a clicking sound came from what I believe was under the dash on the passenger side and a few minutes later, it started blowing air out of the vents again. Is this the blower motor or could it be a bad relay? Any other ideas what

I have a 1998 Ford Explorer, the air coming out of the vents stopped coming out of low speeds and only came out on high speed. Now it does not come out at all. it comes out the rear vent just fine.

I have a 1999 Chevy Silverado. The air conditioner blows cold air but it barely comes out of the vents. The problem is not the temp of the air but the pressure.

Why does the air compressor still run with the air conditioner on even though there is no freon in the system?
