97 town country lxi blower motor resistor block

I have almost 1/2 of dash taken apart and can not locate resistor block. I
assume its somewhere in inlet plenum only have 3 fan speeds out of 5 for
front hvac blower motor. I have replacement but can't locate original
resistor block's location. Thanks

 

Well that's interesting.... Open hood. The Block is located at the back of
the engine compartment on the passenger side of the vehicle under the wiper
module Against the firewall.

Dear maxpower, thanks was just where you said it was. appreciate it my
local dealer tech said it was under dash and had to be taken out. looks
like I needed dash out any way wires severly charred especially red/white
light blue and light green connecter melted was on way to meltdown. from
some of previouse messages under stand there is additional wire to
purchase to correct problem is this covered by a tech bulletin for the
fix. thanks again.

 

If you purchased the part from Chrysler you should have gotten the new
harness with the resistor

to maxpower, Yes I purchased the resistor from Chrysler dealer, no wire
harness was with it. Looking at wiring diagram I think that 12 gauge wire
was used on power side of motor with 40amp fuse. Wire between resistor
block and blower switch only control resistance to ground using between 12
gauge to 16 gauge wire smallest wire for greatest resistance. doesn't make
sense to me being in series resistance is additive. Will check monday with
dealer almost makes me want to use 10 gauge for all 5 wires and get a good
ground. Resistor had significantly degraded with resistances of old
significantly higher values than new resistor may have been straw to melt
the camels back so to speak. You have been tremendously more helful than
my local dealer and I appreciate it. Its hard to find good information in
an age of misinformation. Where is a source of trouble codes for HVAC
computer. I know that panel can be reset with top and bottom rear wiper
buttons. Does chrysler use a special instrument to diagnose or do lights
give codes by sequence in which they blink. Again sincerest thanks you
greatly minimized my frustration!!!!!.

 

when you contact the dealer have them un the part number to see if they gave
you an old part number without the jumper harness or have them run the part
thru Star Parts.

We do use a special scan tool to access fault codes from the BCM and by the
lights blinking.

Any answers on this one? I'm going to do the block in my 2002 T&C this
weekend.
Thanks,
