after replacing the evaporator core left headlight, blinker, and taillight do not work?

There is a ground G203 at the left side of the dash kick panel, I would check this first. If that is okay let's check the fuses, this guide can help:

I checked the plug that goes to the lights, and I am not getting any power to the left side lights and the right side has power.

Did you check the ground I have mentioned?

Ken L, yes I have they are all tight.

Okay, when you did the job did you remove the BCM? I would try checking the plugs. Also, let's try resetting the computers by following this guide:

If this doesn't work, we need to run the codes by doing a CAN scan. You can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.

Here is a video to show you how:

Ken L, I just put it in the shop, and they found that the fuse in the #3 spot on the fuse panel in the dash was missing but it is fixed now. thanks for the advice.

Did you remove the fuse? I don't understand how the fuse can be missing?
