BLOWER MOTOR WILL NOT RUN
Check fuses. Turn ignition switch to RUN position. Check for voltage at function control switch. Switch blower switch to HI position. Check for voltage at switch and at high-speed blower relay. Ground blower motor with ignition switch in RUN position. If blower operates, motor is okay.

Check the blower motor fuse 30amp in engine compartment fuse center and blower relay in right rear in engine compartment-

Do this -you can power the blower motor purple wire and see if it works direct from the battery postitive post-
