When the blower motor resistor fails the blower switch defaults to the high position. autozone.com has a great tutorial on how to replace the blower motor resistor.

realfixesrealfast.com has a segment on blower motor resistors.

2001 jeep grand cherokee,heat and a/c do not bloww hot or cold air


Bernard,

HVAC failure
the car has 2 classes of HVAC< manual and ATC
the blower must blow on high.??? does it on high?
if not, check fuses, for blower. (if lower speeds only fail say so)
the blower is dead,
then say if dash controls are Manual or ATC<
atc = automatic temp,controls with a dash thermostat et cetra.

the diagnostic path is different.
the ATC has self test too. .with over 30 errors possible.

use comments to respond, not a new post. please.

zero air flow.
#1 is bad fuse fan.
if it fails on high , the fuse is blown,
replace it or test it with a an ohm meter .
DMM meter. select, ohms Rx2 (low range)
zero ohms is good, infinity is bad.
a 100% accurate test. every time.

fan fuse blown.
fan bad
wire to fan bad.
controls to fan bad
input to controller bad.

use a voltmeter to find this.

there is no way to guess. only do tests. the FSM covers it.

Fan speed control only powers HVAC blower on high 2005 Jeep Chero


Not usually too difficult, but once you locate it, you'll see. Some are under hood at firewall on passenger side area, and some are right on the housing under dash on passenger side, usually close to blower motor connection.

Heating system


This is obviously a heater system control problem, I beleive this system is vaccuum controled with vacuum acuators that open and close doors in response to the climate control system comands.

Listen for the sound of escaping air from under the dash board, esp on the drivers side. Look for any unattached hoses under the dash. From there if you do not see anything obvious, you will have to obtain a schematic of the HVAC system, understand it's opearation and then start testing the vacuum control devices. maybe more than you want to do.
