    I have a 2000 jeep grand cherokee, I have had to replace the wiring harness that connects to the blow box twice already. The wires are actually getting to hot and melting the harness. When it first began it would wokr then stop working and then work again. Now it doesn't work at all.

You have to change the resistor (little box that the blower wires goes to) it is held in with 2 screws you will need the harness (($15) as the factory one was a defect and last you need to change the blower motor as the factory one draws too much power and burns up the resistor and harness..this is what i did on a 2000 grand cherokee with the climate control and it works great..I tried to fix the harness etc but it will still go out again if you do the above you will not have any problem with the blower working at random it will work better than new.I think jeep has retards for electrical people, has anyone had problems with the junky taillight assembly??

It could be a fuse. but you have to find the reason why that fuse blew. it could also be the resistor connected to the blower wiring. it is near the blower. it is a small gadget not an "electronic' resistor.

Heater blower not working


You call it the blower motor, I assume you mean the interior Heater/AC blower motor. When the motor acts as you have described it is usually a problem in the motor itself like a short or rectifier.

REPLACED BLOWER MOTOR CONTROL MODULE...Now blower is working but not very much air flowing out of vents! Fan speed is working...it heat and cools. but still not adequate air flow from the vents ..2000...


check your blower hoses to see if one or more have come loose or got redirected or the selector switch isn't functioning properly (is it blowing better on defrost as opposed to floor vents, or forward vents, etc.)
Good luck

2000 Jeep Grand Cherokee, heater wont blow heat!


Check the thermastat or your cooling fan to make sure all is working good. If your engine cant warm up, you will not produce any heat inside the car

My 2000 Jeep Grand Cherokee's fan does not work. No heat/air/cool air is coming out of the vents. What is wrong?


Could be the switch that controls the fan or the fan its self. Possibly a fuse has blown. All are a fairly easy fix

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.

The blower doesn't work for heat/defrost


If you have Automatic Temperture Control then you will need a blower resistor module which could be around $100 to $200. If you have a manual temperture control then it can be just a simple $20 blower resistor.
