A/C question

[travis2822]

My A/C seems to work fine. The other day I could here the blower motor blowing but no air was coming out. I turned off the A/C for about 20 minutes and when I parked there was a giant puddle rolling down from A/C unit. There is usually a little drip but nothing to be alarmed about. It's a 99 4x4.

It sounds like your evaporator iced up not allowing air to flow through it. When the ice block melted, it made the giant puddle, and you probably got your air flow back. Low evaporator pressure along with high humidity is the only thing that will cause the evaporator to ice up. Any one or more of several things can cause low evaporator pressure. The most likely cause would be the clutch cycling switch is out of calibration and needs to be replaced. It is located on the accumulator, is very inexpensive, has one connector with two wires in it, and no tools are required to replace it, (hand tight). Hope this helps.

Edit: Also make sure the drain hose is clear.
