         1) Remove radiator fan motor relay from relay box located at

right side of engine compartment. Check for continuity between relay

terminals No. 1 and 3. If continuity exists, go to next step. If

continuity does not exist, replace cooling fan relay. See  Fig. 8.

         2) Using a fused jumper wire, connect battery voltage to

cooling fan relay terminal No. 1. Using another jumper wire, connect

cooling fan relay terminal No. 3 to battery ground. With cooling fan

relay energized, there should be continuity between cooling fan relay

terminals No. 4 and 5. With cooling fan relay not energized, there

should be no continuity between terminals No. 4 and 5. If continuity

does not exist as specified, replace cooling fan relay. See  Fig. 8.
