6th Gen ('00-'05): Fan blowing wet air
#1
Fan blowing wet air
I used the fan this morning (I usually use the AC) and noticed it was blowing wet, sticky air. Yesterday I got the 'low coolant level' message.
The passenger side carpet is dry. The heater core was replaced six months ago.
How is coolant or water getting into the vent system? Where is it coming from?
Thanks, Mike

not a expert, but have you had it checked for intake leak?
While researching top swapping I saw videos of tons of 3800 with coolant going where it doesn't belong.
I need to figure out where my oil is going. Just before each oil change get light and is not even on the dip stick. Only known leak is oil pan gasket and it gets done on Thursday

Could be a cracked plastic heater/coolant bypass elbow. The two elbows are fairly near the cabin air filter and when they leak they often spray a fine mist into the engine compartment that could be drawn in through the cabin air filter air intake. Those leaks usually don't show up on the ground under the car since they're so fine and don't leak unless the car is running. It's a very common problem. If that's the problem replace them with the aluminum ones made by Dorman, found at any auto parts store.

I made sure to get aluminum during intake repair

Well the car is back from the shop. I had the plastic coolant elbows replaced with metal, the electric coolant fan switch replaced, the thermostat replaced, a new coolant level sensor replaced, and new fluid. $400.
After the mechanic changed the other things and filled up the coolant, the light was still on. That's when he replaced the sensor. It was probably just a bad sensor all along. I wanted to replace the elbows and thermostats need to be replaced from time to time but $400? grrrrrrrr

I never noticed you having an issue with the low coolant light. Usually it is just a gummed up sensor.
I honestly just unplugged mine, and check level the old fashioned way.
Did you ever get your cabin air filter checked out?
