I got in my truck this morning and there was a musty smell, I looked at the carpet and the carpet on the passengerside was all wet. It has not rained here for a long time so I know it is not a leaky window or windshield. Does anyone know what could be causing this?

If it's not antifreeze check the drain for the AC plenum.

Are you using the a/c (or any feature that runs the compressor?). If so check the nipple on the firewall under the hood. I bet it's running back on the nipple and down the wrong side (the inside of the cab) of the wirewall. I had this happen and a 3/4" heater hose tied down by the frame fixed it. I went ahead and took out all the seats and carpet and dried it out right. Kept it from molding that way.

I appreciate the response and will check out both tonight.

Thanks again

Mine was/is doing the same thing. In feeling around I noticed the grommet around the drain hose was deteriorated so I put some gasket maker around it to try and seal it up. I still need to run my a/c and see if that fixed it or not. If not then I'll go the hose route. Didnt have any hose at the time.
