hello i have a 98 expedition wife went out to drive it today and when she started it and turned it off the heater fan wouldn't quit running with the key off i looked at it after work today and found out when i pull the fuse number 15 on the inside fuse box it will power down when the key is off i also noticed when the heater fan had power that so did the turn signals in the manual it says generic electronic module and pats module . also when i pulled the fuse the dome lights don't work untell i turn on the key. does any one have a idea whats wrong ? also about 1 month ago the wife plugged in a cell phone charger into the cig lighter or power spot and she was hearing a sizzling sound around where the cig lighter spot is she said and then the air bag light comes on and under the dash is a box that has 2 relays in it and it was taped up a blue one and a black on when i pull the black relay the heater fan will stop and with the key off i can put in the relay it will stay off tell i turn on the key then it wont turn off . and i was hearing a noise from the pass kick panel that sounded like the warning buzzer and screeching sound so i pulled the kick panel off and used a piece of hose to find the sound and it was coming from the air bag module so i pulled the 2 sets of wires going into it the air bag module.i went out and drove it i went 6 miles and turned it off in 2.5 miles it fired right up i was reading that the pats would only let you go 1/2 mile and shut off . can any one help thanks kelly
