Hi,
New to the forum and I'm in need of some help. Around a year ago I install HID's on my 2004 GMC Envoy SLT XL suv, everything was going find for like a month or two. Then the problem started my HID's lights started flickering, when back to the shop were the HID's were installed and to tell you the truth I have no idea what they did, but i got pissed off and had them remove the HID's because no matter what they did the lights were still flickering. So I had them put my lights back to normal but I'm still having problem with that too, my headlights turn ON of OFF while driving at night or daytime. I purchase a new battery and alternator had them installed and my lights are still turning ON and OFF. I'm running out of options and I don't know what else to do. I want to install new HID's lights but how can I if I'm having all these problems. I also notice that when I'm raising my windows all my exterior and interior lights dim and my RPM accelerate by it self. Can you help?
