Freaky AC blower
Past few days, when I start my truck ('99 F150), occasionally, the blower for the A/C doesn't come on right away. Hit a speed bump = comes right on. I'm thinking loose connection, but where? Anyone?

two places to test for bad or weak contact the blower motor assembly itself do wiggle test at the motor wire connector engine compartment passenger side near fire wall. and the other place to test is the fan speed selector switch you have to open up the dash to get to it...and on other thing to look for is a bad ground strap..blower motor will have one going from it to the fire wall..and the dash has several to body ground and then look for body ground to frame..
