Looks like you have replaced just about everything...But, don't forget that the mode selector is also a switch (vent, bi-level, defrost etc) If that switch is not connecting, nothing will work. Did you test the components you changed, or just changed them using the process of elimination method? Put a volt meter on this stuff and determine where power is stopping.
Good luck

Fan motor on heater has stopped when I switch between the settings ( defrost to upper & lower heat) I hear the gates moving but the fan won't come on ( no heat ) it's very cold please any sugestions...


first check the heater fuse...then you want to unplug the fan motor lead and run it straight to the battery...if it works then you will need to check the resistor assembly..it is located on the heater housing right near the fan..it controls the different speeds for the fan and usually has 4-6 wires coming off it. If these don't fix the problem...try looking in the fuse/relay box both in the cab and under hood to see if you have a relay for the heater fan...as it may be defective

95 jeep Cherokee heater wont work but rear window defrost still works need help please


Check the blower motor fro good connection, power and ground. Hot wire it to the battery and see if it runs. Check the blower fuse, relay, switch and resistor pack.
blower and rear defrost circuits are totally unrelated.

Replace switch but the heat won't turn on.and it's not the fuse..95 jeep cherokee sport


Most likely the blower motor,it has gone out,some times,not always,you can bump the blower motor with your hand,and it will start to run,or it will try,if so,replace the blower motor,otherwise,check the voltage at the blower motor,if it has voltage,replace the blower motor,if it has no voltage at the blower motor,then replace the blower relay,located near the blower motor.

2003 jeep, grand cherokee no heat or blower


this sounds like the blower or switch is bad. to test blower, first check the fuses, then if it still does not work, run 2 wires from a power source 1 for positive and 1 for negative(ground) disconnect connector at fan motor and try these wires to see if it runs. if not replace fan,if it runs on wire but not from switch, replace switch. or check wiring carefully.

It sounds like you have an issue with your fuse block. Pull the fuse for the radio and remove the buzzer. see if this changes the situation.
