The car's fan does not blow air in position 1 or

check what fuse is blowing
I suspect that it is a fuse for the fan relay that switches on the radiator fan
if that is the case , replace that relay
the reasoning is this
there is a fuse for the coolant temp sensor
that sensor reads the coolant temp and reports to the ECM so that the air/fuel mixture can be adjusted correctly
there is a second fuse for the control for the fan relay
when the coolant temp reaches a set temp , the ECM through that second fuse energizes the fan relay which starts the fan to cool the radiator
from your description , the short is in that system and so I suspect the relay is faulty
take it to an accredited auto electrical specialist for a diagnosis of the fault

How hot is the engine running in degrees f? Does the radiator fan run?
With hvac turned on, check voltage and ground at the blower motor. If good voltage and ground, suspect the blower motor is faulty.

cooling fan relay could be bad,check relay by making a fuse jumper wire.look at the relay control circuits on relay look for control circuits terminal number 85 and terminal 86 hook fuse jumper wire terminal 85 on relay to good ground and take terminal 86 on relay hook up a jumper wire touch battery positive terminal relay should click if not, relay bad.

does it blow heat? any fan at all?

Check your fan fuse and fan relay.

It could be the fan fuse, fan relay, a bad control head on/off switch or the blower motor is bad.

I think u may have an air temperature control blend door problem, the door is moved by a small electric motor, it is stuck in the cold position.

Hi! The speed control is defective.The terminal 1&2 could either b worn or burnt out.

I assume when you say the ac fan you mean the condenser fan? Take the plug loose from the fan and check it for voltage.If theres no voltage when the air is on,check the relays and fuses.If there is voltage then replace the fan motor.

looks like fuse # 8 "heater control relay- ac clutch relay-cooling fan" fuse runs the 12 volt side " black and yellow stripe wire " pcm or ecm runs the ground side "red -blue stripe wire"- what else do you need?

First, turn on the fan motor to high, and then tap the bottom of the motor. The brushes stick to the armature, and tapping the motor will release them. Second, check for voltage at the connector for the motor. It should be 3 VDC at position 1, 6 VDC at position 2, 9 VDC at position 3, and 12 VDC at the highest position. No voltage at 1/2 & 3 = replace the heater resistor, located in the air box between the fan & the heater core. No voltage at all? Replace the fan switch.
