2005 Durango 4.7L 81,000 miles

Asked by Jun 09, 2010 at 12:38 AM about the 2005 Dodge Durango SLT

Question type: Maintenance & Repair

Hello all, I have some questions that I need help with. Here they go.

    I have a 2005 Durango SLT with 81,000 miles, and also have a stereo system that includes an amp, subwoofer, aftermarket radio and capacitor.

    1. Lately I have noticed that the A/c in the truck does not get cold while at a standstill like it used regardless of the heat outside. It does get cold once the truck begins to move again. What could be the cause and solution?

    2.  Wtih the A/C it is understood that the truck surges when the compressor engages and disengages, but i also notice that the lights inner and outer dim low and regain normal brightness and the radio (aftermarket) sometimes shuts on and off when the compressor surges. What can cause this and can i replace the factory installed alternator to a 160amp alternator to compesate for the power loss from the sound system?

   3.  Also could changing the serpentine belt be the issue? I know the belt squeals alot when it gets wet (More than normal) and also when the engine starts when cold.

Any help is appreciated, Thanks.

Yeah it could be the serpentine belt since it drives the alternator that makes power for the battery. Change the belt and the tensioner and see if it will get better. You can also check with volt meter to see how many volts it is producing while running the motor it should be over 14 volts.
