YES -
Go to step 7.
NO -
Replace the fuse(s), and recheck. If fuse(s) blow again, check for a short in the No. 12 (40 A) and No. 30 (10 A) fuse(s) circuit.?
7. Connect front blower motor 2P connector terminal No. 2 to body ground with a jumper wire.
8. Turn the ignition switch to ON (II).
Does the front blower motor run at high speed?
YES -
Go to step 9.
NO -
Go to step 24.
9. Turn the ignition switch to LOCK (0).
10. Disconnect the jumper wire.
11. Disconnect the front power transistor 4P connector.
12. Check for continuity between front power transistor 4P connector terminal No. 2 and body ground.
Is there continuity?
YES -
Go to step 13.
NO -
Check for an open in the wire between the front power transistor and body ground. If the wire is OK, check for poor ground at G507.?
13. Connect front power transistor 4P connector terminals No. 2 and No. 4 with a jumper wire.
