Re: High Beams - some questions Posted by Ari [Email] ![]() ![]() In Reply to: High Beams, Rich Cook, Sun, 26 Mar 2006 15:20:26 Members do not see ads below this line. - Help Keep This Site Online - Signup |
The headlights go through two components - the headlight relay, AND the pictogram module (aka Orange relay). The Orange relay is just a straight pass-through. And it really isn't a relay. It has current sensing to turn on the pictogram if a bulb is out. I haven't personally seen any failures, but I have heard of people having failures in it. Rare.
The other is the headlight relay. It can fail numerous ways, the most common being failed solder joints. That's because inside the relay, there is a circuit board with the actual relay. The relay is held onto the board with solder, so the weight of the relay, under vibration in the engine compartment, causes the solder joints to crack. Re-flowing the large solder pads usually fixes the problem.
My questions-
If you pull the stalk, do the high beams come on at all? Do they wink on and off by themselves?
First, remember that the headlight switch has to be in the ON position (all the way right) for the high beams to do anything but flash. And with DRLs, it can be confusing as to if the headlights are really on.
After that, it could be a wiring issue (or bad connection) so that the headlight relay doesn't know the headlights are on.
So - if you pull the stalk, do the high beams come on at all?
