4 Wheel Drive/SUVs/turn signals

Question
The hazard lights on my 1999 Jeep Cherokee Sport work however when I use the turn signals they do not work; no flashing indicator light on the dashboard either. The bulbs are OK as is the fuse, so I'm assuming it is the turn signal flasher, however I cannot locate it.

Do you think this is the problem and if so, where is it located? (cars I've had in the past, I've been able to replace it pretty easily).

Any help you can offer would be appreciate. thank you!

Answer
Al,

I don't have a manual for your model, but the flasher unit, is usually located on, or near the fuse box.  Sometimes the turn signal flasher, and the emergency flasher is part of a single unit, even though they function separately.  

I suggest to most of the people with wiring, or vacuum line problems that they purchase a repair
manual (around $20) for their model Jeep.  These manuals give step by step instructions on most repairs, along with diagrams of most controls, such as the vacuum lines, wiring, and switches.  These manuals can come in handy for future trouble shooting.  They can be purchased at most auto
parts stores.  If you don't want to purchase the manual, many stores will let you look up problems such as this if they have an unsealed manual.  Another way to check this out, would be to call your local Jeep dealer, and ask a shop person where the flasher is located.

Will discuss suspensions, lifts, lockers along with tire suggestions. Trail ratings and possible requirements needed for specific type of trails. Safety equipment and what you should carry with you. Certified off-road instructor. I am not a mechanic, and 4-Wheeling is a hobby, so if I can't answer a technical question it is due to my mechanical knowledge being related to vehicles that I have owned, or have worked on. I do not have manuals on all vehicles.

Experience

40 plus years of 4 wheeling in a variety of vehicles. At the present time, my major off-road rig is a 94 Jeep Wrangler with a spring over and a 1 1/2" suspension lift. This gives me a total lift of 7" or so. I have lockers front and rear. I have removed the track bars, and sway bar for maximum articulation. I am running a stock 2.5 ltr 4 cylinder with a Jacobs ignition along with a cold air high flow filter. It has 4.56:1 gears with a Dodge NV4500 transmission along with a 3.8:1 Atlas II transfer case. This gives me a final ratio of 105:1 in low gear/low range. Other vehicles I own, are a 96 Ford F-250 with a 6" lift, posi rear end, 36" Hummer tires, 5 speed with a fuel injected 460 ci engine, an 87 Samurai with an 8" lift, Ford 9" rear end with a spool, Chevy Dana 44 front end with an electric locker, 5.88 gears, 16% reduction in high range and a 6.5:1 low range with 35" Baja Claws, and a stock 2003 Grand Cherokee Overland. Trails I have run are the Rubicon (10 times), Dusey Ershim, Fordyce Creek trail, McGrew trail, several trails in Moab, Utah along with local monthly runs.
