first symptom was the headlights going off and on, so I ordered and installed a Dorman lcm repair kit that piggy backs onto the lcm to bypass the problem. when i did this, my problem multiplied. Now, the following are not working, rear window defogger, illuminated entry, horn chirp when locking with remote control, door panel courtesy lights, a/c compressor, power mirrors, instrument cluster (gas, voltages, temp and oil pressure, odometer, trip meter). I removed it and put in another LCM, now the only thing i've fixed is my headlight problem. it's like half of my electrical system has just shut down. any ideas?

Check body grounds and have the BCM checked.
