Question about 2003 Chevrolet Silverado 1500
Relays go bad also. Try to sway relay with another relay next to it. May have been the relay all along.

there is a loose ground and or wrong size fuses for the air
if loose ground you will want to have a certified mechanic trace the grounds back to source
i dont think it could be relay but there is a way to check this
find the relay panel in the engine compartment open it
find the relay that says air conditioning
pull it out
now there are numbers on that relay
in that same relay box theres relays about 6 to 8 of them that look similar to the air conditioning relay
this is where the numbers come in if the numbers match switch with other relays
mark the air conditioning relay with black marker or nail polish so you know which relay is which
if its the relay thats bad the new relay from the relay box put in its place will work fine
put the old one back in the slot where you took out the other relay out of and then proceed to dealer to purchase new relay for your vehicle if the relay was the problem

it may not be the blower motor. it may be the blower motor control module which use to be the resistor. it's located under the pas. side. remove the black coyer , 2 scaews above the pas. foot area. then remove the blach unit that has a purple wire going to the back of the motor on the right. price about 140 dollar with tax.

Temperature Control Blend Door Failure No Heat
In all modern cars there is a tiny DC electric motor driven gear drive that moves a plastic door that blends heated and cooled air from the AC and the heater core, this is called (interestedly enough) the air temperature control blend door actuator. The motor that moves this door fails because the door starts sticking from warping, most common complaint is no heat but it can be no AC as well. To replace these parts (blend door and blend door actuator) you must remove the entire dash from the car. Always have this problem confirmed by a dealer or qualified repair shop as it is a very expensive repair.
