    What model truck?

    Low motor speed is usually due to a worn motor or a poor connection at the motor or resister assembly. Does the motor work on all speeds but it's just slow? Does it seem "noisy"?

    Might even pull the motor out of it's housing and look inside the housing. I have found them full of leaf's and stuff. Blocking the air flow. Might make sure it does not have a cabin air filter. I have found them when owners did not even know they had them. If you have no high blower, the resister or relay could be toast. I had a Monti Carlo that had a bad junction plug in the wires leading to the motor.

    In the summer I had a similar problem.
    It started out by the fast blowing speed not working then slowly went 4,3,2,1.
    My truck is an 06 and I had the warranty, it only took the dealership 15 minutes to fix (they told me 3 days over the phone, lol). So it couldn't have been to complicated if it only took 15 minutes to fix.
