I change the turn signal lever I took apart unplunged everything carefully put everyhing back together carefully but as I was workig on it I heard my horn honk twice I look no bear wires anywhere finish putting back together went to try it turn key no crank noise turn ligths on only parking ligths came on stop ligths work radio works dome ligths dont work dashboard ligths work and security warning ligth stays on. Whats wrong? thanks for nothing I new it was A rip off!!!!

check shift linkage --if idle high will also cause gear problems

Something not plugged back in or loose connection? Heater core replacements are time consuming and a lot of electrical has to be disconnected to perform the procedure

Its either the flasher's, the turn signal lever switch or the hazard switch.
Try pulling one of the flashers out and see if the other system starts working.
Has anyone installed aftermarket electronics or tampered with the wiring in either system? Like an ALARM system? Stereo?

Looks like the same problem I had on my 2004 Lumina. If the brake lights all work but not the left AND right signals both do not work it is most likely the flasher which is under the driver side of the dash. If you barely move the turn signal lever and the right or left turn on briefly then it is the switch OEM part number 26093875 verify the numbers to match your vehicle. The switch is located in the steering column and can be changed out in about 30 min. Be careful on keeping track of how you take it apart and put it back together.

You need to go to the part store and buy a special tool that compresses the spring inside the steering column. Don't cut corners, Disconnect the truck's battery. Without the tool you will not get the column back together. With the tool you will compress the spring, remove the clip above that dust shield. and then start to pull it apart. Remember to put everything back together how it was. That dust-cover looking thing must go back exactly how you found it or you will damage the plastic pieces to the horn circuit. When you pull the cover off for the horn be careful with the wire. Push and turn counterclockwise to remove. And you will pull out the directional lever and unscrew the little Phillips head screw from the hazard button so the turn signal Assembly can be moved so you can access the screw that locks the key cylinder in place.

Hello,
I just solved this problem on a friend's car two days ago, however, it was the right turn signal...based on knowing the inner workings of the switch, I'll bet the fix is the same though. If you are not very mechanically inclined, replacing the switch would be the easiest solution. The part was going to cost 100 dollars locally, so I took apart the switch and fixed it. There are three phillips screws on the underside of the steering column. Remove these screws, pull down the wheel tilt lever and pop the plastic shell off from around the steering column. There are two screws that hold the turn signal/headlight switch on, remove these screws and remove the two electrical connectors from the switch assembly. On the front side of the switch assembly are two more phillips screws, remove these and snap the switch open...there are two plastic tabs that keep it together, be careful not to break the assembly or you will be buying the part. After you get it opened up, take out the actual lever that controls the signals, look down in the switch assembly where you see a white plastic block through a small slot in the shape of a quarter circle, most likely there is a black plastic peg snapped off inside there. Use a small pair of needlenose pliers to remove the peg. Look on the signal lever and you should be able to see where the peg snapped off of it. Go down to harbor freight and buy a kit of very small drill bits (four dollars, item number 94606) and a tube of super glue (sku number 42367). Take one of the small drill bits (I think I used the 1mm or the 1.2mm) and drill a hole in the center (underside) of the small snapped off peg (do not go all the way through, go 3/4 of the way through). Take the same bit and drill a hole in the lever where the peg was snapped off, again, go 3/4 of the way in, but not all the way. The plastic this is made out of is pretty hard, so drilling it might take a while...also, the bit is pretty small and may not fit into a drill (I had this problem, and so I just used my fingers to turn the bit...it took a while, but it works fine...patience!). Once you have both holes drilled, use a pair of side cutters to cut off the shank of the bit short enough to fit into the hole on the lever and allow the peg to fully seat onto the lever. After you are SURE it is short enough (but not too short, or the peg will just snap back off), use the super glue to glue it all together. Let it sit for ten minutes or so and put it all back together. This works great, costs about 6 bucks (much cheaper than replacing the whole part), and I would assume it is stronger than a brand new switch.

What i can recall the only removable electronics is the complete turn signal assembly or the other would be the electronic piece that is actually the key reminder buzzer that reminds when key is left in ignition while engine is off...This looks like two flat copper match sticks attatched to a 1 inch piece of plastic... Well enough of my guesing.. if you were to go to an auto parts store and look at a motors repair manual for a chevy steering column little if anything has actually changed in the design with the tilt steering column which is probably why you originally took it apart because of the tilt torx bolts coming loose... I hope you used locktite when you reassembled to makesure it doesnt happen again....Good Luck

i have the same problem in my 1998 Montero and was surprised to see your posting. I just went to an auto electric expert and diagnosed it as a broken turn signal switch that needs to be replaced.

you need to take the upper and lower steering column covers off, should be 3 screws in bottom, take tilt steering lever out if neccessary, it is a 2 peice cover, take apart, change switch and put back together
