    Was driving home from the mountains last night and the recirculate wouldn't work. When I had the A/C on and pushed recirculate the A/C stopped blowing. Pushed it again and fresh air worked. Today the A/C doesn't work at all. I heard the fan clutch engage but no air blowing through. Is this the fan relay?

    Got it. Question though. WOuldn't the fan motor be on blowing hot air? If I don't have a leak in the system how will it lose charge?

    Thanks

    Mine a 2012 seemed to lose it over time I had the dealer do a test to see if it was leaking and they found no leaks. the air wasn't hot just what ever the temp was coming through the cab.

    There is no clutch on the blower ( fan ).

    Is the clutch on the compressor working at all?

    Does the AC LED indicate it is in AC Mode?

    Is air coming out of the vents?

    Is the blower running?

    It seems you have the burned connector on the blower motor problem which can be repaired cheap.

    Blower connectors:

    Look at both connectors on the motor. I'd be willing to bet one or both of them are burned.

    Check the plug that goes to the resistor connection and the white plug that goes to the motor? If they have burn marks you need to replace the connector plugs.

    Part number 90980-10916 Connector

    Part Number 82998-12380 Wire and terminal

    Not sold as a kit, sold as each. So you will need one of the plugs and two of the terminal and wires.

    Connector:

    Terminals:

    You may also have a burned resistor connector and may need these:

    Plug Number 82141-04M40
    Resistor Number 87138-04052

    Jimmy, thanks for this. I can hear the compressor engage when I push the AC button.
    Yes, the LED lights up on AC and recirculate.
    No , air isn't blowing through the vents and I can't her the blower/fan blowing.

    Thanks

    Check the connectors on the fan blower.

    Thankfully it is not the compressor. Usually the resistor.

    Okay, so here's a new question for the same problem. The fan sometimes works and sometimes it doesn't. Checked the motor (under the dash, behind glove compartment) and fan spins freely. Turned the fan on after and it spun. Now the fan works intermittently. Doesn't spin as well as it previously did. Is that the motor wearing out? Or a faulty or weak connection?
    Thanks for the replies.

    I would still say it's the resistor but I'm a retired foot doc. lol.
