I lost my wipers, blower motor, ac compressor, and cig lighter. All the fuses are good and have power. Is there something else that supplies power to those components...perhaps a blower resistor or something?

Check the connection block under the left front of the cab. Sometimes they are a bear to get working again. We wired around them.

Karl, There was a mod for the cab relay on the board down by the starter. Check the solenoid down there for voltage on both sides when the switch is on. The starter type solenoid was replaced with a socket assembly with wiring and a Bosch style relay. The later 2290 parts books list them in a box on the relay board parts page.
