    I have a 2010 Tundra 5.7 and for a while the blower will fluctuate while on hi. I've not noticed changes in volts during operation. I'm r thinking the blower motor maybe going out? Any other advice on what it could be?

    I’m having the same issue, but it fluctuates on any speed. Replacing the blower motor worked in another vehicle that was doing the same, so I think that’s the way to go.
    I’m looking for a good aftermarket replacement motor. It seems the OEM ones don’t last and are weak.

    The blower motor resistor is what sends the voltage to blower motor which adjusts the speeds. As you turn your fan speed switch, the resistor changes either reduces or increases the voltage to the blower motor. They are easy to replace and cost around $25

    This is a super easy swap on our trucks. I think i spent 30 minutes on this swap.... it took longer to get all my tools out and then put them away than the actual job itself. My blower was fluctuating too and now that I've put in a new blower.... it's actually blowing more air, (I think mine was on its way out for awhile). I suggest changing the in cabin filter as well during this.

    Replaced the blower a few mis ago. So far, so good! I think that must have been the issue, but it normally takes 30 mins or so of constantly running the AC before it would crap out. I’ll assume it fixed it for now.

    Gents,

    I know these are posts from last year, but they’re helping a lot thanks! TXTundra2722 surprised you and I are having these issues a bit more than the 2010’s (no offense to the 2010’s) but they are older. Mine is a 2019 CM SR5 5.7 and I’m having similar intermittent AC issues. Today, full fan speed on the dial was blowing as if it was on the first click, then stopped completely for a bit. Then it came back on but real weak.

    there’s a YouTube video from A1 auto where dude says the resistor is built into the blower motor for 2014-2019, but, there’s another vid showing a resistor that is separate. Ugh. Frustrating since I probably have to replace both. Thanks for the info!! Love this forum….

    I wonder if this would fix the problem in my '07... when I start the truck, even if the dial is on high, it takes about 10-15 seconds to get going. The blower blows, AC is cold when it's on, heat is hot, defroster works, but nothing comes out of my forward vents when I turn it to that setting, cold air only comes out of the vents that are right on top of the dash near the windows. I think it has more to do with the blend doors, though. Would this new blower fix it?

    Anyone worried about this repair, don't be. It seems once a year or so when I'm out of town a small leaf gets into the blower and makes a racket until I can drop it and clean it out. I've done it in random parking lots with a #2 phillips only in OR, WA, and CA.

    Is there any difference in access between "grade" trucks with the column shifter and the fancy ones with the center console shifter? Mine's on the column.

    Did you replace the blower and resistor for this problem? Did it fix it?
