Im sorry if this has been posted before somewhere on these forums, but i am kinda freaked out about my truck. Today my AC ran great, i changed the oil and it ran perfectly throughout the night, until around 2 am after i went to a friends house. I started my truck and turned the A/C to full setting, and i had this loud humming noise coming from behind the glove compartment. It was blowing somewhat cold air, but nothing like it had been blowing 2 hrs before. Im not sure what could of happened, but now it blows real soft and has that huge humming noise behind the glove box. Any way to find out whats going on?

Thanks

 

something fell down the holes in the dash!!

 

does your friends house have a lot of trees around it? and is their a lot of leaves that fall from them. that may of gotten into your blower and causing the noise and little blowing power

 

I have the 2002 Dodge Ram 1500 QC, and i had/have the same problem. There was a TSB (Technical Service Bulletin) put out to correct the problem. I took my truck in, and they replaced a part. But Months later, the problem resurfaced, only now, i have extremely cold air on the drivers side, and warm air on the passenger side. I would take it to the dealership and have them look at it, while its still under warranty. If i find the paper work, ill send you the TSB number.
