Right blinker how do i change the blinker bulb on my chevy venture?

Bad wiring to the rear tail light cluster.

check that you have a bulb tat has only point of contact because if you have a stop tail bulb in there or a duel point contact bulb for a return earth it will short straight to earth

may be you should make a diagnostic and you can do it in a garage or you can do it by yourself if you want to do it by yourself you need some tools and you can find some good ones here: chinasinoy.com

check for power at one of the back light sockets. You need a circuit tester which is basically a screwdriver with a lightbulb inside and a test lead than can attach to various circuits. You can clamp on the one of the leads going into the bulb and touch the screwdriver shaped part to a grounded part of the vehicle....say a metal bolt on the body. If the light goes on...you probably have a bad ground. Which all your lights use in the back! Which would explain why they all went out together.

Good luck and be careful.

check if front bulb is ok may be burnt must replace or have wiring checked
and check fuses again may not be making good contact

check the gruond in the black wire in the blinker switch if its ok, sometime the after market parts have ashort life time try to replace the flasher switch ( blinker switch)

check for a short it could be anywhere in the line

remove the white slide on hedlight assembly and light will come out and you can change bulb

turn the turn signal on and then just get out of the van and look at the front one and then the back one

Typical problems like this are usually related to the turn signal switch, or the bulb. However, it is possible that you have a loose connection in your turn signal housing. I would check the housing and wiring going to the bulb, first!

IF you rule that out, then next step is turn signal switch. This will be replacement of the unit.
