    I purchased a 2014 a couple months ago. The other week I noticed a heater only works on high. No other speed is functional. Still blows heat and AC, but only on high speed. Any ideas where to start?

    On my 06 I had the same issue. I had to replace the AC blower resistor (under the passenger dash) and it went back to working perfectly. Apparently it's a somewhat common problem.

    Also, check the plug that plugs into the resistor. After reading about it, I was able to get all speeds working again after wiggling the plug. Worked for a couple weeks, then it quite again so I replaced the resistor and wired in a new plug.

    A trick to get it to kick on is hit or bump the fan underneath the glove box. I've replaced my resistor on my 2010 a few years back and it worked great. That being said I now have to bump the fan to get it to kick on again so I'll need to replace that part again.

    Awesome thanks for the helpful inputs! I'll try giving her the ol 1-2 when I get off work lol. I was hoping it wasn't something I had to dig too deep into for repair. Resistors arent too spendy. Thanks again!

    Anything other than full speed has to go thu the resistor block.

    Resistor and connector needed:

    [​IMG]

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

    If they have burn marks you need to replace the connector plugs.

    Part number
    $10 90980-10916 , 6"es 12 Gauge Wire Harness
    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.

    Thank you! I got all the parts. Unfortunately when I ordered
    $10 82998-12380 90980-10916, 6"es 12 Gauge Wire Harness
    82998-12380, only one wire came with it and they charged me $10.00 for one friggen wire! Unbelievable! So frustrating! I still can't believe the audacity of charging $10.00 for a part that probably costs .03 cents to make. What a rip off! Anyway. Thank you for your help! Much appreciated!

    Well as I said in my post above:

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