I replaced the old corroded Dimmer switch and discovered I still have problems. The headlights burn fine for 3 or 4 minutes and then go off, after about 15 or 20 seconds they come back on. It does it while on Lo or hi beam. I have had this happen on older cars before but never on Lo Beam and replaced the dimmer and it was fixed. Is there a thermal overload built into the dimmer switch? The Hd Lights are new Sylvania Halogens. A week or so ago when I first checked the lights I had to cycle the switch several times to get them to come on. Now they come on every time. Not sure if I have a bad switch or if maybe the new Advance Auto dimmer may be bad. Any Thoughts will be appreciated.
