    slowly??? When the fan/anything blowing into cab I get a smokelike looking coming through the vent. It doesn't have any smell (it did give me a headache though)...When the truck is just running and no fan is on, the same smokelike stuff is coming out of the fan box under the hood. I am guessing it is freon, could it be something else????? /forums/images/graemlins/confused.gif

    If it was freon the system would be empty in a few seconds with a leak that big. It could be a electrical problem like a burnt wire at the blower motor.

    It can be freon. I have seen an evaporator leak for a week like this. It's fairly common.

    A good a/c shop, or repairman if you know one, could inject dye into your system to look for leaks. It is for use with a blacklight to spot freon leaks . It is generally inexpensive just to have them look. Then you could decide what to do . By all means this forums members are important so please find out what it is for your health, you said you got a headache from it.

    It could be that resister for the fan speeds,Freon is oderless and would give you a lightheaded feeling..........

    Mechanic looked at it today and told me it was the heater core...asked if the windows fogged up, asked if coolant level dropped...both yes. Found a VERY SMALL amount of coolant on passenger floor mat. Now I get to change that!!!! /forums/images/graemlins/grin.gif
