Chvy Trailblaxer and no AIR or FAN. Also No WIpers. HELP

For the no fan/AC, likely you have a blown blower motor resistor, located under the glovebox. Order the pigtail also (a must). Careful when ordering, depending on whether you have manual or digital controls, the part is called blower motor resistor OR blower motor control module, both look the same, but are very different. Have the check engine light check and see what code/s are popping up and report back. That switch under the steering wheel, is called the ignition switch. That won't cause these particular problems.
