How do I get to tail lights?

what year corvette? it would help to know?
if its a c4 you remove the license plate and bracket , and back-up lights, and use one arm thru the space they used to occupy and possibly one from below and its still a major P.I.T.A. due to limited clearances a shop manual will help a good deal

chiltons is not a shop manual, its only cliff notes on a shop manual, but in this case the shop manuals not much help, it says all the tail light bulbs can be reached from the license plate mount area,once the bracket and backup lights are removed.... that makes me think they never tried it themselves, or the access space would be 2" wider than it is currently to allow half decent access

ok I had the same problem and its a total p.i.t.a. but it can be done with the license plate and mount bracket removed for the inner one and the car up on jack stands or a lift for the outer one
and yes its a solid 8 out of 10 on the cussing index unless you've got some 12 year old , or a small and helpful wife with smaller arms and hands whos willing to get dirty helping you work on the car,with skinny arms helping

Corvette - Corvette Stop/Tail & Turn Signal Light Bulb, #2057, 1984-1996

1984-96 (C4) #2057 Stop/Tail & Turn Signal Light Bulb



Corvette Stop/Tail & Turn Signal Light Bulb, #2057, 1984-1996

They are very similar. The Multi-function Switch is the turn signal switch or Directional Signal/Hazard Warning Switch Assembly in the attached schematic. Operates turn, hazzard and high beams.

The Stop Lamp Switch is always connected to the rear lights, unless a turn is requested. At that point the Stop Lamp Switch connection is broken and the requested turn (Left or Right) is connected to the Direction Signal Flasher. The other side remains connected to the Stop Lamp Switch. This way if a right turn is selected, the contacts in the Directional Signal/Hazard Warning Switch Assembly that are between pins M, N and P are the ones we are interested in. Pin P is the input from the Stop Lamp Switch and supplies battery voltage when the brake pedal is depressed (Stop Lamp Switch closes) to the OFF contact, because a right turn was selected in our example, pin N is no longer connected to the OFF contact, but is now connected to the RIGHT contact and pin L, which goes to the Direction Signal Flasher and the right tail lights flash. Pin M is still connected to the OFF contact and the left tail lights light solid as long as the brake pedal is depressed. Obviously if a left turn is selected, this is reversed and if no turn is selected, both pins (M and N) remain connected to the OFF contact and all tail lights light solid if the brake pedal is depressed.

To troubleshoot the Stop Lamp Switch (Brake Light Switch), verify battery voltage to ground from the orange wire. It looks like you did that with your test light and it was good. Now check for battery voltage between ground and the white wire. Same as the first test, but move the one end of the test light from the orange wire to the white wire and push the brake pedal. If no light, it could be out of adjustment. Try the tests again with the switch unmounted. The orange and white wires are connected to normally closed contacts and the brake pedal opens them when in the at rest position (brake off) blocking current flow to the Directional Signal/Hazard Warning Switch Assembly and no brake lights until you press the brake pedal and the switch is allowed to close and the current can again flow to the lights. This means that with the switch connected, but not mounted, the contacts should be closed and the test light should light on both the orange and white and the brake lights should be on.

Try it and see what happens. If not we'll move on from there.

Thanks.....Shop manual says to remove wheel and interwheel housing seems like a lot of work to change a tail light. :roll:
 
It's FINALLY done it only took 2 engineers on tech and 10 days great design One with their hand through the plate one through the bottom of the fascia and me pulling on the fascia.
 
Unfortunately, that's about typical for a c4, but you'll at least be much more experienced and faster if you ever need to repeat the process now.
