Turn Signal Problem

On a 99 SE 4 Cylinder, the turn signals went out completely this morning on the way to work. I tried the emergency flashers when I got to the office and only the front left one would go, and very rapidly.

I went inside and got my flashlight. The fuse (10 Amp behind the glove box) looks good. I tried them again and now the turn signals work normally. I tried the emergency flasher again and they work fine too except the front right one doesn't flash. The bulb is good since it works fine with the regular turn signals.

Ideas? Intermittent failure of the flasher(s)? A haunting? It sounds like the flashers are somewhere up under the dash in front of the driver, is that correct?

Thanks.

Your flasher should be on the bottom area of your steering column along the inside edge,

Thanks. Looks like it isn't one of those cheap round ones you can get anywhere.

The dealer wants $115 for the flasher. Is there a generic part that fits? That is ridiculous.

Im showing the factory part number as "56009339". I ran the number on Napas website and it interchanges to a napa part number NF EP27 for like $24.

By the whole unit, do you mean the black box blinker on the steering column under the cover?

Before you spend tons of cash. It could just be that you are no longer grounded and it is causing sporatic flashing. My 04 was doing the same thing and when I took off the rear flashers to see what was going on. There was corrosion around the screws. Those screws apparently serve as the ground for the turn signals. I put one size larger screw in each of the lights (left the other ones the same incase I need to do this again) and *poof* the problem has disappeared. Just an idea. It might save you some cash...saved me some.

I agree with 'Loo' on this. Try testing the grounds using a grounded jumper wire to each signal. You have grounds on the front of the jeep make sure those are clean and corrosion free. I have had good luck with the multifunction switch from advanced auto parts, Jeep is just too expensive.
