Running the air conditioner and the air stop blowing out of the front vents but blow in the rear. It blows out strong in the back on the car could there be a fuse blown. 04 GMC Envoy

could be a number of things . such as switch stuck air flapper or fan motor.

Could be a blend door problem under the dash.

Could be a blockage in the lines to the rear unit.
Might be low on freon too. Or a blend door problem.
Can you check under the floor and see if one of the lines is cold ?

I recharge unit for your ac

Hi. Have your car aircon evaporator cleaned. Check also the drain hose. All water should go out of the car through the drain hose. There might be something clogging up the hose that is why water will run out the floor and that causes also the aircon to work intermittently.

Have a good one!

maybe blower motor for front is getting weak

climate unit is bad

Check and replace the right side temp-controller.

the resister block needs changing... oddly enough i'm unsure of what fan you are saying is not working.... if it's the front.. the resister block is located on the duct work under the dash for the air... near the fan... you will see a connector going into the side of the duct work. two screws and the block comes out... should be fairly obvious for the rear one but it will be near the fan.

Hello according the the manual, the back vent are to blew cold air only..the fronts vents are suppose to the entire car...
