Your problem is most likely the turn signal relay im having a problem similar to yours but when my signals wont work neither do my hazards
try replacing all sets of fuses for the hazard and the tail lights.
Check the fuses and it may be the flasher relay as they have 2 try turning the hazard lights on and off a few time as you relay may be stuck.
you must have a blowed fuse.
check your bulbs some bulbs have two filament on them one may be out and the other working.
Yes
No they did not come factory equipped with daytime running lights.
check your clutch and brake fluid
Turn signal flasher?
If your 1999 Ford Expedition has turn signals that do not work but hazard lights that do work, it is likely that you have a fuse that is blown. You might also have a wiring issue including exposed wiring.
Lights or signals fits this 'fill in the blanks'-type question..
Is the hazard lights button not on top of the steering column ? The switch for the hazard lights on my 1995 Ford Explorer is part of the multi functin switch ( turn signals etc. )
If the turn signals on a car works but the hazard lights do not there may be a problem with the flasher switch. The flasher is located in the steering column, and a damaged unit can cause the lights to stop working.
