The High beams on my cMax are erratic.  they will come on and off, mostly off.  Dealer says there is a short in a control module and the only way to fix it is to replace the whole Headlight assembly ($416).  This does not sound right.  I look at the parts for the assembly and there is nothing listed as a control module only the bulbs and the housing.

What the SA may be saying is that there is a short to ground diagnostic trouble code in the control module (likely BCM), and have traced the short to the headlight assembly. I can't look it up until next week.  A couple of thoughts, you can buy the assembly for less than $416.  Before  I would replace it, I would remove it and troubleshoot the assembly for the short to ground.  Again, I won't be able to look at the manual until next week.  The dealer won't try to find issue / fix assembly.  They only replace parts.

If it must be replaced, you should be able to get one from a wrecking yard.  I had to replace a rear outer tail light and it was 'only' $100.

My post was lost in the hickup the site had.  Here's the two attachments i discussed.   So, you should be able to test the headlamp assembly using the wiring diagram and multimeter for a problem with the circuity in the assembly.  I don't want to run through it again.
