I have recently bought a 2002 Eldorado(only 40,000 miles) the only problem so far is the left turn flashes about three times faster than the right. I bought a flasher but can't find where it goes, I pulled the lower panels off but can't see it. It sounds like it is directly behind the headlight panel but no way to get to it from underneath. I figured I better leave it alone and see if someone on the forum can help.

Re: Turn signal flasher
Not sure how you get to the flasher, but you might get access through the side panel. Looks like as you suggested it may be behind the headlamp switch. Not sure on your model, but my headlamp switch just pry's loose and pulls straight out. Might get in through there as well.
I will check the bulbs tomorrow although it looked like the were all flashing rears anyway and at least one in the front so will start there. Thanks for the info, I will let the forum know what I find.
If one side flashes normal and the other fast IS NOT THE FLASHER!.
The flasher does not have a left and a right side circuit, is only one circuit, the turning switch directs the signal from the flasher either to the left or the right side bulbs.
The flasher has a current sensor inside and is set to flash at normal rate when the current drawn is equal with what 4 light bulbs will normally draw (1 bulb in front and 3 in the rear). If the current is less (say only 3 bulbs are working) then will flash faster to indicate to the driver that one or more bulbs are out (either burned or not making good contact).
So what you need to do is put the flasher on and check all the bulbs, you should have one in front and 3 in the back. I repeat there are 3 bulbs in the taillight, is not enough to see some light flashing you must be sure that all 3 bulbs are flashing. Also you must pay attention to the intensity of each bulb, it may flash but may be dimmer. If that's the case it means it has a bad contact (mainly ground).
Again is NOT the flasher, the flasher works fine, is doing what was designed to do, is indicating that one bulbs or socket or wire on that side has an issue.
Just for your knowledge (for future repair, but I repeat this is not the case), the flasher relay is located underneath the dash board on the right side from the hood release handle, accessible once the driver's side kick panel is removed (it is clipped on and surrounded in a foam wrapping).
