Gang,
anyone familiar with the electronic touch climate control unit? No matter what mode I'm in (econ, auto, etc) the fan is on hi speed thru the vents. I pulled the board out in the engine compartment where I hoped to find the resistors for the different blower fan speeds but found a pc board full of components instead. After doing some troubleshooting of this board, it seems ok. So I yanked the control unit from in the dash. Without a schematic, one would guess "HI" would be a full 12 volts, "LO" would be 4-6 volts, and "AUTO" would be any voltage between the others depending on the temp chosen. Well, "HI" and "AUTO" seem normal. On "LO", the voltage jumps all over the scale. OK,OK, too much info! Anyone have a schematic or another unit I could swap test with? Then again a big Frankenstein movie high voltage knife switch on the dash may be in order.
Thanks
