There is no air coming from the HVAC?

Hi,

When you turn it on, do you hear the fan motor running or is there no sound whatsoever? Also, does the vehicle have manual or automatic climate control?

I attached a pic below from the wiring schematic. Check to see if the two fuses I highlighted are good and have power. Both are located in the under-hood fuse box.

Let me know.

See pic below. Note: Pic is from the manual climate control schematic. If that isn't what you have, the schematic is irrelevant.

yes, my fuses are both good.

Do you hear the blower motor running? Does it have automatic or manual climate control?

Let me know. I hope you had a nice Christmas.

Joe

No, i don't hear anything at all.

Hi,

I need to know if it has automatic or manual climate control. I need that so I can inspect the correct wiring schematic.

Let me know.

Joe

it has a manual control.

Hi,

Okay. I need you to start by confirming there is power to and from the 40-amp blower motor fuse in the under-hood fuse box.

Power from that fuse (which should have power at all times) goes to the blower motor relay which is located under the dash and mounted to the HVAC box close to the blower motor. I need you to check the red wire at the relay for power.

If that has power, the next thing I need you to check the heater AC fuse in the instrument panel fuse box in the vehicle. This fuse should only have power when the key is in the run position (engine can be off).

Start with this and let me know the results. Also, I attached the wiring schematic for this system so that you would have a reference.

Let me know what you find.

Also, I have wires that are of interest highlighted for you.
