## Discrepancy

(CAN) WHILE TROUBLESHOOTING AN UNRELATED AUTO HEAT SNAG, THE MAINTENANCE CREW DISCOVERED THE FORWARD BLOWER RELAY P/N JC-D1N (K136) IN AN OVERHEAT CONDITION. THE RELAY APPEARED BURNT AND WELDED SHUT. THE SOCKET IS ALSO IN POOR CONDITION. THE LOCATION OF THIS RELAY IS IN A HIGH TRAFFIC AREA, JUST PRIOR TO ENTERING THE COCKPIT.
