Heater Fan on my 98 Town & Country doesn't always work

Yup, take the cover off the bottom of the heater box, pretty simple, just take out the screws of the black box on passenger side underneath the dash. you will see it, it's round. There's not but 3 or 4 screws in it. After you remove the cover you will see the back of the fan (The round motor end) Take out the fan, amke sure the unplug the one connector wire after the fan is out. When you have it out take a hammer and tap on it. You will see all kinds of black dust coming from it. Try to tap all of the dust out. After the dust is almost gone or completely gone that you can see, replace the wire, turn the switch on and make sure the fan isn't going to hit anything and turn it on the lowest setting, should work great now. Turn off the switch and put it back together. Should work at least a few more years now

Chuck thank you! I did what you said and it worked like a champ afterwards!

Good, I'm glad it worked for you George!!!!!! Work on getting you a backup fan, you should be able to do it once or twice more before you have to replace it Anyhow, glad I could help, and thanks for the reply back to let me know! Much Appreciated!
