What steps are needed to remove and replacece the turn signal assembly? Mine is getting so loose that it is difficult to use. 2002 GMV Sahara,

If memory serves, you need to remove the whole fascia (basically the front end of the car) It's not difficult, just time consuming. There are about 12 or so bolts of various sizes that need to come out, along with popping out a few plastic pins. The headlights also need to be removed to allow removal of fascia. ( just the two 7 mm bolts on top, and assembly will be loose. I don't think they need to be taken all the way out, just loosened)
A/C condenser is bolted to front of radiator, making the removal of the radiator the hardest part of this job. Almost forgot, fan assembly needs to be removed also. Tranny cooling line removal also difficult. Mine didn't have the additional oil cooling lines, but some do. Hope this helps!

Open back hatch
Remove screws holding the lens on
Apply some force pulling it out side to side because the have alignment pins that are a little stuck
Push in the thumb lock and turh the wire connector on the back to remove bulb holder
Reverse of removal
Hope this helps

1. Step 1 Purchase a replacement bulb from an auto parts department or auto parts store. The bulb number is 4157NAK. You also can check the parts book or ask store employee for assistance.
   
2. Step 2 Open the hood of the vehicle. The hood release handle is located under the dash on the left side of the vehicle. Once you discharge it, you must free the second hood release under the hood of the vehicle in the center. Move it to the right and lift the hood.
   
3. Step 3 Locate two headlamp retainers (clamps) holding the headlamp in place. Pull up to remove them to discharge the tabs on the assembly.
   
4. Step 4 Detach the power to the headlamp. Now you can easily remove the assembly out of its position.
   
5. Step 5 Take off the rubber cover located in back of the turn signal light. This will allow access to the bulb socket.
   
6. Step 6 Turn the light socket counterclockwise to remove it from the assembly.
   
7. Step 7 Remove the old bulb by holding the bottom of it and pulling it gently up. Replace with new bulb.
   
8. Step 8 Once you have replaced the bulb, put the light socket back in the assembly and turn it clockwise to secure it.
   
9. Step 9 Replace the rubber covering on the back of the headlamp assembly.
   
10. Step 10 Put the headlamp assembly back in place by sliding it in the slot and attach the power supply.
    
11. Step 11 Replace the retainer clamps to hold the headlight assembly in place and close the hood of the vehicle.
    

This is not a trivial job. I would recommend you get all four bulbs for whatever side you are replacing - do them all. The dealer-dude didn't have the orange turn-signal bulb in stock, and said they don't see too many replaced. I guess thats probably right since it was about ten years ago when I last saw someone actually use their turn signal.

So step one - go get 3 (or 4 if you replace turn signal) bulbs. The front marker and side marker are the same bulb type.

Step two - remove the middle grill. The top connectors are visible and you can use a flat-bladed screw driver to compress the side or top and jiggle them so they pop loose. One you get the top part of the grill loose - DO NOT just pull outward - you will break the non-visible two lower connectors and get to go to the dealer again to get new ones. Instead, to remove the grill once the top part is loose, PULL UP. These light gray lower connectors are inbedded in the Head Lamp assembly.

The exterior trim piece is next. The two top black poppers need to be jimmied up 1/4 inch and then they pull out. The trim piece has 3 additional attachment points that are hidden. About the middle and a few inches to the outbound side, there are 2. They have an outbound facing notch, and the trim piece needs to be tapped towards the outward direction (side of the car) until it is free of them. This piece can flex a bit - its OK - but don't overdo. The final attachment is at the outermost corner that is a 1/4" male that plugs into a female fitting - This can be carefully pulled out and the trim piece is off.

The next part is the Head Lamp Assembly. There are 3 screws which the owners Manual actually correctly identifies. These come out. And the assembly is basically loose, but attached by 4 cables going into the Assembly. The Marker lights and turn signal are easy - just untwist them. When you reconnect them - they have VERY different slot keys, so you won't have trouble remembering which is which. The tough one is the headlamp.
The connector to the bulb has a rubberized cover. You can't see it while it is in place,but it has the word "PUSH" and two arrows on it pointing at the sides. You need to press in on the sides, a little higher than the middle, and disconnect the bulb connector. I had to gently use channel locks to do this.

When the connector is removed, you can remove the rubber dam material surrounding the light. It may stick, but this entire thing will come off, making removal of the bulb a much simpler task.

Once this is removed, you will see a wire latch holding the lamp in. Squeeze the wire latch (like pinching a clothes pin - kind of) at the top and it should release the bulb, which can now be simply removed from the enclosure.

Replacement is the reverse and will be much easier now that you see all the parts that were previously hidden.

Or you could just pull out the relay under the hood, it's marked fog lights, pull the relay out. If your hi beam indicator is flashing with your fog lights on them selves. Could be the multi function switch. That controls turn signals, headlights, fog, I have seen many of those go bad.

Mine did the same thing. One light I broke off in a snow bank and I just cut the other wire. Problem fixed :)

if you have ll the screws out then you just need to work it out. there a ball on the lens that pops into a socket on the frame. if it never been removed its a bit of a struggle

In Audi models with with light switch on the stalk with the wiper switch and turn signal switch this is a common problem. The switch is bad and needs to be replaced, you have to replace the complete assembly with the turn signal and wiper stalk

I had the HARDEST time with the lights...I never realized changing a bulb would be so difficult. Once you unscrew what you need to, go into the trunk and pull the lining away from the back part of the light. There are the white prongs that you will need to tap with a hammer until they pop out and then the light assembly will come out. Be careful though, I got a little too impatient and broke mine. I used a binding agent to hold it back in place though...GOOD LUCK!

*The Turn signal on the Side of the car next to the headlight*
1. Open the retractable headlights.
2. Remove the plastic shroud around the headlight: two screws in front and one on each side.
3. Look to the outside of the headlight and you will see a single screw in a small plastic cover on the front inside edge of the signal light assembly. The headlight prevents you from getting at the screw straight-on. I broke it loose with an offset phillips screwdriver, and then backed it out with a regular phillips.
4. Remove the plastic cover, and you will see two screws. Remove them.
5. Now you can pull the turn signal assembly forward and out.
6. To remove the bulb holders from the assembly, twist counterclockwise and pull out.
7. Pull straight outward to remove the bulbs. To assemble, follow the steps in reverse. Note that there are two plastic rods on the back end of the turn signal assembly that you will insert into two holes in the channel of the fender

*The turn signal in the bumper*
1. You will need a phillips head And Flat head screw driver, right below the turn signal there is a panel that you can pop out, (or its allready gone, Looks like a Fog light can go in there.)
2. once u find that, (Pretty easy to find) Look directly up in there., there is styrofoam up there and u will also notice a little hole,
3. Stick the Phillips head screw driver in that hole and turn it counter clockwize, The screw will not fall out,
4.once it feels like the screw is loose put the flat head in between the turn signal lense and bumper, the side where you unscrewed it and SLOWLY pry it out,
4. once out, just twist the plug and replace light bulb
to replace just reverse instructions
