how else can I get ahold of you? I'm having heater problems, I don't have the time to hunt for the problem, I'm thinking its in the vent tubing, the insulation where the pieces meet other pieces is wore out, and falling apart. I need to figure out a more detailed solution. my problem(s) are/is I only get heat out of the left side, and cold air out of the right, regardless of the heater position. it started after my fan control switch went out, I rigged it so it was constantly on, and thats when the problem started, I replaced the fan control switch, so the fan turns on and off when it's supposed to. but until today, my heater would heat the left vents for a minute or 2, while the right were always cold. and today the heat stayed constant but faded from hot to luke warm.

any ideas?
