If it is working at all then the relay and fuse is good and the problem is either the little vacuum hose on the back of the control switch panel or the panel itself.

2004 Chevy Silverado 2500HD ac stopped blowing we changed motor and resistor and still nothing we have cold air running when u drive down road but no pressure


I'm going to assume you have the manual control version. The relay in the resistor allows the fan to run on high and bypass the resistor circuits. There is a 40amp blower fuse for high speed and a 30amp fuse for the other speeds. The motor is grounded thru the resistor.
Do you have power and ground at the motor on any of the settings ? ?

if you got heat on all speeds and the blower motor is working properly then you probably need a new HVAC switch.

SOUNDS LIKE THE SWITCH & OR THE BLOWER MOTOR RESISTOR, ARE THE PROBLEM WITH THE LOWER SPEEDS. SPEED 5 MAY HAVE ITS OWN FUSE, REFER TO OWNERS MANUAL FOR INFORMATION ABOUT THE HEATER/AC FUSE.

Why doesn't ac blower work on number 5 setting? it is a chevy hd gas engine


Most likely the blower motor resistor. It's mounted next to the blower motor under the dash. Also check the 7 wire plug going to it, GM had a problem with that plug, and the wiring getting hot and melting. The plug is $68.00 from the dealership. One of my customer's car had the same problem.

Heater/ac switch speeds 1 and 2 don not work in 99 Silverado


you need a resister found under your air duct by the passenger floor under dash board auto zone sells these for about 25.00 you may as well buy cabin air filters while your at it . 1 of the screws will be a pain to install back into the duct work I left mine out didn,t make a difference . you might have to order it as they are a comman item oh you will need a vacuum to clean up mess from cabin air filters .this is not a hard job .
