My mechanic told me it cost about $500. I have spent $1100 on a left blinker.(This does not include the junction block.) They finally said it was the junction block. The blinker works but other things don't. Now I am getting the runnaround about a new one that is on back order.
try replacing all sets of fuses for the hazard and the tail lights.
Check fuse Check stop light switch - usually located at the upper end of the brake pedal under dash area
Have a 2003 jeep grand Cherokee trying to fined the junction box took covers off steering column but can't fined box.
Have you checked for the flasher unit for hazards not sure where to find it on a cherokee.
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.
Make sure hazard switch is pulled all the way out May be a problem in thw steering column
hazards and turn signals have separate flashers. replace flasher for turn signals
replace fuse and hazard flasher
