    Both left & right turn signals work somtime; other times don't work at all. I checked bulbs and all four are on when turn signal handle is activated. Where is the flasher located on this car?????

    I have a slight variation on that problem. The flasher does flash both left and right lamps, so the lamps are good. The left turn signal works, the right does not but the right turn signal indicator in the instrument panel remains lit (not flashing) any time the ignition switch is turned on..

    My 1999 Cadillac Sedan Deville's turn signals will not flash. I bought flasher replacements at both pep boys and autozone and both of these places told me that there are two flashers listed on their computer for this model but they both only had the one in stock (same). I,ve changed this one twice with no luck, as well as checked all the bulbs and related fuses. Strangely enough, during this time as Ive been dealing with this for the past 2 months, flashing the signals the only way I can (by lifting and lowering the arm up and down to simulate the flash) there has been a couple of times where they just started to work again. This has lasted as long as a few hours and as short as a few minutes before just stopping again for no apparent reason.Any advise would be greatly appreciated. thanks Dan M.

Take off the black plastic cover under the dash above the brake pedal, 2 9/32 screws hold the front edge to the bottom of the dash. The flasher is located behind the dash above the parking brake. it has a metal clip holding it to the dash about behind the trunk release button. You have to reach around with your hand to find it as it is hard to see. Once you unclip it you can pull it down to unplug it. I just did this job, once you find it it's easy. Napa carries the replacement flasher $13.19. Good luck!!

I have tried to find the signal flasher also, And looked under the dash after removing the cover below the stering wheel, this exposed another panrl, aluminum cover to remove, After removing this 2nd cover I looked up below with bright lights and could not find the signal flasher to replace? I purchased the part from NAPA No 34. Assuming this is the correct replacement, I can not find one under the dash to the left of the stering wheel column as Haynes Repair manual also states that location?

I have no signal lights, left or right, on my 2000 Oldsmobile Intrigue. I was having a problem with a front bulb not contacting properly making the right signal flash rapidly. I left it flashing while

Check if your emergency flashers still work. You possibly need a new flasher. Some cars have separate flashers for turn signals and emergency flashers, but some they are both together. If your emergency flashers still operate leave them on and find the flasher (follow the clicking noise the flasher makes) and see if there is another flasher right next to it. swap with the emergency flasher and see if your turn signals work again. If so, replace the faulty flasher.

Where is the turn signal flasher located for a 97 cadillac deville.

to the left of the steering collum connected to the under collum kick panel as you take the panel down it'll be connected to the cover, It's not a genaric flasher, it's square and looks like a relay585157684.jpgCost about 6 bucks at the parts store. If the turn signals aren't flashing and they do come on, and may be they flash on one side and not the other then it's not the flashers fault. All the light bulbs have to work or it won't flash and thats how you know that thiers a bulb out. Turn on the four ways flashers (Hazard lights ) and walk arounf the car and see if thier all working and flashing brightly. They'll flash anyway on four way the switches are known to hang in hazard and not work right on turn signal so try switching ti a few times and maybe it'll straighten out. If it flashes at all the flasher is good and if they don't even light not on hazard or turn the flasher and or the fuse is bad.

1990 Cadillac Fleetwood Left turning light or emergency lights go on but don't flash. The right turning light flashes well. If I turn the handle not all the way left and move it a bit the left light begins...

You most likely need a new blinker switch - the emergency flasher is also most likely bad - there is one flasher for turn signals - and one for the emergency lights --
Replacing a blinker switch is best left to the pros --
also - Take down the Vin # and call the local dealer - - ask about recalls and Service bulletins.

1996 cadillac sedan deville blinker stoped blinking

I assume all lamps are tested to be ok.
1) Check fuse A11 in trunk (10A) is ok,
2) Check turn flash enable relay 'F' in trunk is operated when vehicle Ign on,
3) Check +12V is present on Lt Blu wire on turn flasher module (LHS steering column) when Ign on,
4) if no fault found during above checks, operation of the turn switch should be checked

1994 devilles flasher location

Turn signal flasher module is behind dash left of steering column near chime module. I have a 94 Seville and I had that same problem you need a Turn Signal Flasher Moduel, I forgot the proper term for it but I had to get mine replaced too. When I hit the signals to turn the side light would come on but the signal light wouldn't. Its a little box you get from Cadillac it only cost like $20 - $25 and you get it installed and trust. It'll work again. I just got mine done this week and my car now has turn signals again.
