Is the belt for the AC broken?

Not that I am aware of.

Well you need to check the ac compressor and belt they are on the passenger side of the motor in the front toward the bottom of the motor. Check for the belt and then turn the truck on and see if the compressor kicks on

I think i am lookin at the right belt slightly on passenger side below motor. and yes it turns when the truck is on. What next? Blows fine just not cold at all and worked fine yesterday

Thanks.

If by dual climate comtrol you mean control in fromt and back. No. If u mesn 2 temp controls in fromt then Yes. How much am i looking atin repairs?

No i dont hear it kicking on and off. Im not mechanicslly inclined so it may kick on amd off i just dont notice or hear it.

Is the cycling switch on the accumulator oily has hell? They are notorious for leaking and if the pressure is too low it will not allow the compressor to operate.

Well they make pretty simple R134a charge kits with built-in gauge for folks like you.

Got to local autoparts store, look for something like this.



Look for the low-side port (it's the only one this kit will fit) on the AC line under the hood and follow the instructions. AC systems leak and after 10+ years yours might be down just enough to keep the compressor from cycling. It will kick on as soon as you've put in enough refrigerant to bring the system pressure up. Done this lots of times and I check my vehicles every Spring and top them up if needed.
