Here is a website that will help you I am replacing mine tomorow. Looks to be straight forward. Although this is for a TJ, I assume that they would be the same. http://www.sonicjay.com/Jeep/relay-howto.htm
Remove the plastic "kick panel" beneath the steering column. There are screws along the bottom. The panel pops off at the top. Next, remove the large, steel plate underneath. The flasher is located high up, to the left of the steering column. You need to remove the two nuts that hold a steel brace/shield that is in the way of removing the flasher. Finally, carefully pry the flasher holder away from metal support over it with a large screwdriver. You will then need to remove the protective tape in order to remove the flasher from it's socket. Reverse the procedure after plugging in the new flasher. It's really not difficult and should only take about half an hour if you haven't done it before. This procedure should cover all Jeep Cherokees from 1997 through 2001. I am not certain if is the same for pre 1997 or Grand Cherokees.
The turn and hazard flasher relays are incorporated into hazard switch.
The 2004 Ford Ranger pickup truck signal hazard flasher unit can be found beneath the drivers side dashboard. The signal hazard flasher unit will be above the brake pedal.
I believe the hazard switch is used as the turn signal flasher in 71 bus. No extra flasher involved... I believe the hazard switch is used as the turn signal flasher in 71 bus. No extra flasher involved...
Both the hazard flasher unit and the turn signal flasher unit are in the main fuse box and are identified
No they are not. The hazard flasher should be located in the fuse panal. While the turn signal flasher is located behind the dash near the AC controls. Can be a pain to find and replace.
The turn signal/hazard flasher is integrated into the flasher switch. A very common failure on these cars.
Incorporated in the hazard warning module part of the hazard switch
There are two flasher relays on your vehicle, one for the turn signals, and one for the hazard lights. The turn signal flasher relay is located below the left hand side of the instrument panel. The hazard flasher relay is located under the steering column support.
