Re: Air conditioner has stopped blowing. what do I check...
Try the 40 amp blower fuse under the hood or the 30 amp under the dash. The check the blower resistor motor under the dash on the passenger side. Check the connector plug to see if they are damaged.

Go online to and google" manuel for 2006 chevy silverado 1500 2wd". Or you can go to ask.com and ask" Where is the resister located on a 2006 Chevy Silverado 1500 2wd". It will give you the info you need.
Had exact same problem with my 2006 Chevy Silverado 1500. Would blow hot air thru drivers vents only and sometimes if I turned truck off and restarted would blow air conditioner for a bit. Rec'd recall letter from Chevrolet in January for this problem.
Likely the resister and or the connection to it on the blower motor located on the passenger side (interior) . Moisture fries it and I had the same problem (common). There is a black plastic cover on the underside of dash that must be removed first. by Gerard Jan 11,2011
With one speed working it is more than likely the blower motor resistor (20 dollar part) located in the area of the blower--needs air to pass by it as it gets rather hot), or at worst case the Module. This part (Blower control Module) is a bit more expensive. Try the resistor first, you can test its resistance at different speed settings to see if it is functioning as it should.
Check the connector to the blower resistor, they tend to burn and destroy the resistor and the connector. Its located near the blower motor on the passenger side footwell.
I would first check the low pressure cycling switch. Next the compressor clutch. I am assiming you already checked the fuses. I hope this helps.
Thank You,

your a/c should not blow cold air-- is the switched turned on inside your truck - yes there needs to be a belt and it a round compressor with a clutch on the front of it - located on the front top side of your motor
