Question about 2003 Chevrolet Suburban 2500
I have a 2003 Suburban, Problem with the left turn signal, the blinkers work sometimes .Only happen with the left side. The passenger side works without a problem. I replaced the multifunction switch it and still the same. What else could be causing this?
The emergency lights DO work, and it doesn't seem to be a problem with any of the bulbs
These functions are all controlled by the turn signal switch, also known as the multifunction switch, this is a common issue you have and will require you replace the switch.

the most common problem is the light boeard in the tail lights usually replace the board full of bulb sockets and that takes care of it but before condeming the board make sure you are getting power to it

Test the circuit board wires on the back side of your taillights where the bulbs go in to see if power is going there with the blinker on, if yes replace the circuit board (quite common with these trucks). If there is no power back there check your flasher relays for each turn signal, assuming they dont click off and on when you tip the turn lever. if all else fails, head for the multifunction switch behind your steering wheel inside the column that your turn signal/wiper/cruise control lever is connected to.

I had the same problem twice before. Solved it the same way both times. In my case it was the Hazard switch at the top of the steering column. It was stuck. I knew it was that because the signal lights had been functioning perfectly until I parked my car alongside the road with the hazard lights on to do some nighttime fishing and sip a little white lightnin'. (just kiddin' about the white lightnin')
When I got back in my car to go, I turned off the hazard lights but I had no turn signal lights! So I kept pushing that hazard button up and down for about 30 times with my left turn signal arm down until it started working again. So after having this happen to me twice, I learned a valuable lesson: Don't ever use hazard signals in this car.

Have you checked the contacts to make sure they have good contact with the bulb base? I have a 1995 Ford Contour. The turn signal went out. I replaced the bulb and it would work when it wanted to. I checked the contacts and sure enough they weren't making good contact with the bulb. I took a screwdiver and slightly bent the contacts a little. It has worked good ever since.
