PT-42 Front Heaters
Sitting here in dreary, rainy, 40 degree cold Texas, I had some time
to poke around the dash board area today. I discovered the alarm switch (turning it on set off a buzzer in the driver's area, but no external alarm). Of course, I don't have the Key fobs -- Later I'll look for the number as someone suggested so I can order a new one. I found the AquaHot heat exchanger -- of the 3 floor-level vents, it's behind the one closest to the driver just below the 2-door shallow cabinet. There was a board on top of it that I didn't remove -- but I expect that the fans are not working on it since no heat comes out. The vent opening to the right (center of the three) seems simply to allow air to enter the dash area, and the far right vent has a flexible AC distribution tube attached to it. I think it may be an air intake of some sort. All the AC/chassis heat outlets (with the adjustable vanes) have flexible tubing attached. There's quite a tangle of tubing in the under-dash area, but conditions here didn't permit me to make an extensive exploration. Since I also have a non- working fan on one of the 2 AH heat exchangers under the galley cabinets, I'll need to get at least one replacement fan. I also found that the internal 'door' that controls the flow of heat/ AC through the chassis system is accessible through the access panel with the passenger's foot rest on it. (In automobiles, this part of the heat/cooling system is almost always nearly impossible to access.) The plenum unit seems to have 3 air pressure (or vacuum pressure) devices attached to the outside. One has a lever arrangement that's exposed -- and some wires (going to the switches above the foot rest) were tangled around it. That may have been why the switchover to AC from chassis heat hasn't resulted in the expected airflow through the 'eyeball' vent as in the past. (We'll see when it's a bit warmer.) I found the alarm system mic "bullet hole" in the mirror above the bedroom closet doors -- but I haven't identified any more mic locations elsewhere in the coach, so far. I find the spot for the LED below the keypad -- but it's a empty hole. Perhaps the LED has fallen inside somehow. (Finding access to the back side of that area looks like it might prove "interesting" as a carpet covered board is on the inside wall next to the passenger seat.)
