Did you use an old switch. Try cleaning your contacts.
Copied from my build.
I went to work on my Light Switch and Wiper delay. I plugged my old one in and the wiper delay worked. But not bright lights. I then tried to combine the 2 and was going to have cut wire and splice and didnt want to go that route.
The Light Assembly I had before was from an 86 and it has another plug my 88 didnt have. I figured it was for some option mine didnt have so didnt think much about it. The white plug is what I am talking about on an 86 in this picture.
Today I got to looking at it (the white plug) and it runs to the wiper handle and I am guessing it is to the delay in the handle. So I then decided to see what I could do about my original Light assembly.
I took the Steering Wheel off. I have had mine off before and have it snug but not so tight I need a Steering Wheel Puller. If you havent had it off, dont bang on it as it will bulge the Steering shaft. Go rent a puller from the parts store. It is free.
You will need to drop the lower plastic panel and I diconnect the dimmer switch and just let it lay on the floor. Remove the Steering Wheel and the covers to the steering column.
There are 4 screws that hold the Light Switch Assembly on. They are recessed. Then disconnect the black clip that keeps all of the wire bundeled to the column and 2 screws that hold the blue connectors to the black tabs /clip.
Once I had it off, I had to take 2 screw out that hold the hazard light switch to the assembly, and set it out of the way. I then had to remove the clear plastic cover so as I could use my wife finger nail file (yeah.. she liked that idea) and went over the little copper tips on the copper layers. Just a couple of times to help make a good clean contact. Then I hit with some WD-40.
Here is a good picture of the contacts that need cleaned and more info if someone needs it.

Put it back togther and everything works great. The 86 and 88 Light assemblys do have different part numbers on them and they interchanged and it got me thru. But it is nice having everything working as it should.
I did take my passenger kick panel off and didnt see a relay box there. Not saying it isnt, I just didnt want to pull the ECM and since I was able to test with a good wiper delay switch, I didnt need to go that far into it.
Found another link to a headlight problem I just wanted to add.
