Front blower will not blow. checked all fuses all ok. did not make any noise before going out. what could it be?

94 CHEVY Silverado ????,heat/ac fan not blowing. K1500?????? Hear clicking when selecting l'm, SET high but not blowing! WITH AIR OR NO A/C? FIRST IS FUSES, MAKE SURE THE BLOWER FUSE IS NOT BLOWN.
EASY NO? CHECK ALL FUSES FIRST. ON ALL ELECTRICS FAILING OF ANY KIND.
BAD FUSE, BAD WIRINIG , BAD CONNECTIONS. OR EVEN BAD RELAYS TO THE BLOWER OR BAD SWITCH BLOW.
THE OLD CARS , HAD A SPEED BLOW , RESISTOR BLOCK
THAT FAILS ON ALL SPEEDS BUT HIGH, SO ITS NOT THAT.
OWN A VOLT METER????
HERE IT IS, ANY OF THIS CAN FAIL THIS OLD
WE USES A VOLTMETER TO FIND THE POINT OF FAILURE.
A SHORTED BLOWER MOTOR CAN BLOW LEFT SIDE TOP
FUSABLE LINK.RIGHT FUSE BLOWN MAKES THE CONTROLLER DEAD.

Have you checked the blower fuse?

Check your fuse for the blower motor and the wires going up to it. Also check connector to blower motor to make sure its not burnt. If all are ok replace blower motor

In the diagram, check fuse 10--40 amp, not only check the fuse, check the fuse circuit for voltage with hvac on. Use a test light to check for voltage. See the wires going to front blower motor, that is voltage and ground, check them both. Also, the front blower module could be causing a problem? The diagram is for automatic hvac.

will it blow air on any setting besides defrost

Check owners manual for location of heater blower motor front,check with a test light,if it's good locate blower motor under glove box and test the two wires for power when switch is turned on,if power is present motor needs changed.if no power check blower motor resister.

There is a HVAC relay and FUSE in the under hood fuse box, have you check both of these? If the blower works on any speed, the blower is good. You say it blows on lowest speed? The blower speed resistor is mounted on the blower housing. The HIGH SPEED BLOWER RELAY is mounted on the blower motor. You may have multiple problems but check fuses first, if all is OK, then a qualified repair shop will need to check further. You do NOT need the whole A/C system replaced. If it does blow cold, thats good, you just need the blower working.

first off make sure you have no blown fuse. but front blower motor may be bad. if it does not work in any speedyou can check for power at the wires going to the blower. under dash on passenger side

Check your blower motor itself, look for power going into it.

Also check your blower motor resistor.
