The blower on my pickup does not seem to want to kick in?

I am going to assume you have already checked all fuses, mini and maxi, so those aren't the problem (I hope you have). So the next step is the blower itself. Take a multimeter and disconnect the power terminal connecting to your blower motor. See if you are reading your 12vdc. If you are (probably if all fuses are working) you may see that the blower itself may have an additional speed control module or thermostat that has gone bad, or fried. OR it could even be the blower's motor itself. So check those areas first. If all is working with the blower section then you may have a problem with the controls or some relay thereof.
