no lights after remote start

I have a 2006 Ford Expedition that I installed a Ford "Gold" remote start security system on. The remote start is working fine, but after installing I have no dash lights, parking lights, or fog lights. Everything else seems to be working. I have checked fuses, swapped relays and still nothing. any suggestions on where to look next. Thanks!

Somebody did not pay attention to the polarity of the light flash wire. There is a burnt trace on the circuit board inside the light switch of the vehicle. Give me a minute I will find the topic with instructions to repair the switch.

Sadly I hate to say you are correct. Stupid mistake on my part. I pulled the headlight switch but mine does not have any visible screws to pull it apart and make the repair. Almost seems as if the face is glued on and the whole back body is formed plastic. Am I just missing them is it possible this switch is not serviceable? Thanks again for all the help!

It had to be put together. It should come apart. Can you take a photo and post it.
