Your saying the blower motor doesn't work? The diagram is your vehicle, manual temp control. See fuse 10--40 amp, check that fuse for voltage, use a test light, key on, hvac on. If no voltage, jump the switch side of relay. to see if blower motor will run. This is just for testing. The switch side of relay, right side in the diagram. Pull relay, use jumper wire between cavities 30 and 87, the blower motor should run. Terminal 30 is hot all the time. Voltage and ground, always check.
