1988 Milano Verde, assistance requested! Over the last week or so the Low Beam headlamps started to get finicky; intermittently they would not come on (always both sides simultaneously), but if I tried again, usually they would; at first I chalked it up to the severe cold snap we had at the time, but now they have ceased to operate at all when the column switch is rotated to Low Beam position. The final failure mode was on for an instant at first switch-on, then they both failed and have not returned since. All other lights controlled by the column switch operate normally, i.e. the Parking Lights/Euro 10 Watt City Lights, and High Beams, all work fine. There's no audible relay click when the high beams come on. Fog Lights work fine (audible relay click at the fuse box). Here's what I've done so far: Research this topic (to include relay recall retrofit info posted by Gubi and Alfisto Steve, among others)=Check. Looking at the fuse box, I believe my car to be a later year model that did not have the Recall Retrofit applied, although there is a relay attached to the door lock relay bracket behind the storage bin to the left of the steering wheel. This is as described in the retrofit bulletin. However, the wire colors at this relay do not marry up to any wire colors at the column switch nor per the retrofit instructions, nor is there any continuity at this relay to any column switch wire, nor is there any any power at this relay when the headlight column switch is turned to any "on" position. Just for fun, I swapped out this relay with several spares I own, but nothing changed. So, column switch=Replaced with a new one, checked OK (Power to new column switch? Check; Power out? Check); Both fuses=Checked OK; Both Low Beam bulbs=Checked OK (Low Beams illuminate when a jumper from the battery is applied directly to the bulb spade); Good ground at bulbs? Check; All wire harnesses inspected for obvious chafing or damage=Checked; Removed fuse box, inspected all connections=Checked; Continuity from headlamp connector back to fuse box? Check; Continuity from fuse box to headlight column switch=Checked EXCEPT for the Grey 1.5mm wire at the column switch. I cannot find where this wire terminates. My dilemma is that the shop manual depicts this grey wire as the one that feeds the low beams through fuses 10 and 11 at the fuse box. The wiring harness colors match my shop manual colors at the column switch until the wires disappear up under the dash beyond sight and reach; but the wire colors at the fuse box connector don't match my shop manual wire colors. According to my shop manual, fuses 10 and 11 protect the Low Beams, but there's no connector attached behind those fuses; just connector spades. The fuses must be ganged to the adjacent connector via bus bar. No grey 1.5mm wire at the fuse box ring out back to the column switch grey wire. Wire colors do match up again to my shop manual diagram up front at the bulb connector. I see no evidence of any PO hack job behind the dash or at the fuse box. There's a bank of relays behind the fuse box, but the wire colors on any single relay don't match the column switch wire colors. Could one of those relays be the factory headlamp relay? My shop manual depicts no headlamp relays at all. Does anyone know where the factory-installed headlight relay(s) are located? I do not want to have to pull the dash to trace that grey wire down.
