2000 LS2 Blower

Discussion in 'Saturn L-series' started by Robert F. Smith, Mar 28, 2008.

  1. My A/C Heater blower started working intermittently. Only the first 3 fan
    speeds now work. When it works the first 3 speeds work well. I was told it
    might be the resistor card so I just completed putting a new one in and the
    same problem exist. Any help would be appreciated. Thanks, Robert.

    Has the dash switch itself gone bad? I assume that you have checked the
    fuses as well. We had a similar problem on our SL2, it was a faulty dash

  3. The fuses are fine. When this first happened the a/c/ was on max and
    working fine. When the car was restarted in this state a few minutes later,
    no blower. It makes me wonder if it is the switch but I am not sure how to
    get the switch out yet to look at it.

    I had a fault in the blower motor that caused a high current. The fuse did
    not blow but the heat caused damage to the fan speed switch and intermittent
    operation. Also burned a couple of connections in the harness behind the
    radio ('01Lw300). The harness wasn't anything that had to be disconnected so
    I cut the wires out of the harness one at a time and soldered them together

  5. Thanks Oppie. I took the switch out and by disconnecting and reconnecting
    the wires I could make the blower work except for speed 4. I will replace
    the switch. I assume it is the whole component that is replaced and not an
    internal swithc. Thanks for your help. Robert.

    I was a bit bummed out to have to buy a entire hvac panel when all I needed
    was the fan switch - somewhere about $150 as I recall :-( To make matters
    worse, the new panel tried to put the A/C on when the mode switch was in
    floor heat position. I was going to troubleshoot it and never got arround to
    it. I did the repair in the summer when floor heat was not needed and didn't
    realize the problem for several months - too late to get an exchange...
