Concealed headlamps will not open when the lights are turned on. Replaced the Concealed relay and having the same issue. If we pull back on the high beams - the covers open but the lights go out as soon as we release the high beam. Any suggestions?
Are the low beams turning on? If not, suspect the head light switch or the terminals in the connector. Check if any terminals are blackened from overheating or if the plastic connector body is melted. If it looks good, also inspect the multi-function switch and connector. If that looks okay, I'll have to dig out a service manual and you'll need a test light or digital voltmeter to do some testing.
