  • Dash fan speed control

    Recently my dashboard fan speed nob only works on high and low. No other levels in between. 04 TJ.

    What should I chase first,

    Speed dial?

    A relay?

    I tried the hammer first; that lead me to believe it's electrical....

    Blower motor resistor. They burn out regularly.
    I've been through 2 in my '02 TJ so far.
    There's been a few posts on this question, should be at least one write-up on it.
    I keep thinking there must be a better way, like installing a new fan system (12v computer case fans come to mind).
    The joys of Jeep ownership!

      I doubt any of the computer fans you'd find are going to be powerful enough for your use... but a thought in the right direction.

        Thanks for pointing me in the right direction. After doing more reserch on the subject, it seems to be a very common problem.

        I did a google search, and man are there the pages on the subject. The local Auto Zone has them for $25. After looking under the dash, I have my battle plan formed. Looks simple enough. 2 bolts, a harnes plug and tight quarters.

        Time estimated to complete = 2 beers.

        Thanx

              I don't get paid till Friday, so it's going to have to wait till this weekend. I'll keep you posted and even try to take some pics to help illustrate the process.

                  The resistor is back ordered. I'll pick it up this week. They are sending it up from another Auto Zone.
