That's too bad
Blower resistor. I have an 04 that does the same thing. Bad connection between the resistor and the plug for me. Big topic though for durango those resistors.
You do not repair them you replace them.

One for front, one for rear.One for front, one for rear.
how do you replace a resister on a front heater blower on a 2006 chrysler town and country touring with a 3.8 motor
under the front passenger seat/ right under the glove compartment
Its your Blower resistor! Its located on the passenger side underneath the dash board. I had to change mine in my 02 Durango. It takes about twenty mins and cost about $40.00 buck. You have to buy it at the dealer.
Check the Blower resistor behind the passenger glove box. I had to replace mine this winter.
They're separate blower systems. Have you checked the fuse?
Find where the fluid is coming out and repair/replace it.
