2006 jeep grand cherokee heater fan not working

When i turn on the car the blower works for about 1 min and stay on a steady speed no matter what speed i put it in to and then practicly dies. I wonder if its the blower power module , where it is located and if its a big job.

thanks christ

when u put it on high does it blow harder?

Try slamming your glove box, My blower only worked on HIGH speed and a simple "fonzie" on the dashboard or slamming the glove box closed allows it to be used on speeds 1-3. I assume its a loose wire or something

If it only blows at high speed, yes it's probably the blower module. You should be able to get at it from under the dash but you need pics or a diagram to see exactly where it is.

thank a lot for the replys,it was actualy the blower module and as you said it's right behind the glove box just remove it and there it is,two screws and a wire.

Blower Module

tzoeric - That is exactly the problem with my blower in my 2005 GC. Thank you for this answer. If only I had seenn this forum before I replaced the whole unit (Dealer suggested) for $200!! And the same this was happenning after the warranty expired!!

Thanks again.:highfive: To this forum as well.

My wifes 2005 GC blower motor issues have been a headache. Lost all but max speed and I replaced the motor control resistor module. That worked for about 2 months and it did the same thing. Replaced the module with yet another new one and it too lasted only 4 months. This time I read where the motor bearings will bog down so much that it created too much drag that the motor needs to pull more amperage than the module is built for. Thus I put in a new motor as well a new module.... ya... that lasted less than 2 month and again back to only having max speed.

(edit - I compared the old motor to the new one and sure enough the old motor bearings were pretty much toast and it would not spin freely. The new motor would continue to spin for a while when you hand spun the cage where as the old one would give you a half turn or less stopping abruptly.)

What do you all think I should look at next? The instrument controls? My preferred option is to buy a for sale sign but she won't let me.

thanks

Wanted to bump this as I plan to work on it this weekend and curious to get some advise on what next to attempt to troubleshoot?

Thanks

Thanks for the advice, just lost all fan speeds except high yesterday at 115,000 miles. Let you know how it goes.

They had me buy a new console before I found out it was the BMR ($200). It stopped working before a year was up, but I reached behind the glove Box and juggled it and it came back on. To me it looks like they jost dont have good contact after a while. It is still working today even though I have a new replacement on hand. Pull it out a little or bend the contacts slightly. :highfive:
