did you check the lines bet. the switch and the resistor mod. Sometimes the resistor mod. have a diferent wiring so if all the signals from the switch are OK in the res.mod. plug, then I will go for wiring in the res.mod.
the fan, no, its a 2 wire fan, ( it is a very simple circuit, need a schematic?)
1- the switch.
2- that 3 resistor fan module
3- the wires <<<<<<<<<<<< BINGO. (contacts are part of wires)
The fan spins directly to the current you are feeding it, on one position of the switch
your car is not feeding current to the fan.
put voltmeter across fan leads.
go to speed 1, see voltage? yes,
go to speed busted, ,see no voltage, yes?
yes, now move that meter lead , RED , back to the next point.
keep moving until you see 12vdc,
the problem will be between good and bad point.
Do you by any chance have the shematics of the fuse box ? I only want to know what fuse goes in what position in the fuse box near the knee of the pilot. My Tracker doesn´t have a cover and I believe there is where they put the drawing of the fuses. Thank you in advance. Carlos.
82corvette: I'm curious to know if you had to buy the whole heater control assembly or just the switch when you replaced yours. I couldn't find a switch on line or at the local parts houses, and when I called the Suzuki dealer their parts man told me I had to buy the whole control unit and the switch wasn't sold seperately. If anybody can help me find just a switch, it would be appreciated. I have a 95 Sidkick 1.6, four door,automatic with a/c. Thanks.
there are some things so outrageously expensive at the dealer.
wrecker parts, or post needs on the classified ad's here.
fan can be tested in place. if runs on any speed, its ok.
if one speed is bad, ( it can be the switch or the wiring)
but most common is one of the three resistors , in a module
that sits in side blower plenum.
see, its air cooled cuz it gets hot , those resistors.
one resistor burns out. then you need a new module.
start by removing the front panels , till you can see it.
the module is part #10 below. just remove part
10 and you will see the burned up resistor.
it will be broken in two ,dangling in side.
see photo of fan unit below:
all this is like:
Jules Gabriel Verne , stuff here, very crude.
