I have a 2000 Chevy Silverado 1500 Pickup. The air flow wasn't going to the correct open-ings. The air force was also weak. The a/c door actuator was replaced & it corrected the flow direction but it did nothing for the air force. Where's blower motor?

Thanks John, but the location has changed. I found it on the passengers side,located behind the glove box inside the cabin duct housing. Very hard to get to. A lot has to be taken apart. I was told by the service manager at the dealership where the door actuator was replaced (cost for it was $350.00+) that the air flow problem was caused by some of the fins being broken off of the blower fan. He said all of the cabin duct would have to be removed to replace the blower motor and fan and the cost would run at least $300.00. I managed to get to the fan to check it but none of the fins on the fan were gone. The air flow problem was actually caused by two side by side filters between the fan and the cooling coil. They were almost completely stopped up. The filters can be removed and replaced by simply dropping down a strap door on the bottom of the duct and pulling down on the filters. The cost of them are about $17.00.
