Small Puddle from a Merc NOOB

I have noticed for the passed 2 days a tiny puddle of water (regular clear water. not coolant) and moisture in my driveway under my car. This has me concerned. Is this simply condensation from the aitmatic system draining water from the compressor and/or bags?

thanx.

any aircon system when running will produce water on the evaporator and drain it to below the car. just watch it when running park.

The Airmatic system does not produce nor drain water in operation. As suggested above, the air conditioning system does both.

I don't see the a/c producing that much water. In addition, I find this water in the morning after the car has been sitting overnight. Hmmm. I'm going to back in the driveway this evening and see if the puddle comes back tonight too. There's an oil stain right there from my dually which needs valve cover gaskets. I wonder if morning dew is attracted to the oil. That would be new to me. I've never seen that.

I guess my spigot was leaking or something. I backed in my driveway last evening and it was dry this morning. Thanx anyway.

I recommend to change your valve gaskets, I had a problem with my injector o rings, making a misfire. I suspect culprit was oil from valve cover
