Can someone tell me where the headlight ground is on a 95 3.0 Aerostar?
When I turn on the right signal,the right headlight begins to flash alternately to the turn signal.
I took the multi-function switch apart to check for shorts,and actually got it back together.Reassembly was MUCH more time consuming than disassembly,however Everything looked ok inside so I'm thinking it's probably a ground problem,but have no idea where to look.Any help would be appreciated.Thanks,David

 

Hi David, the Grounds for the Headlights and Turnsignal are located as follows:

Right Headlight - G100 Top rear corner of RH fender apron, below hood hinge
Left Headlight - G105 Front of LH fender apron,left of battery

Right Turnsignal - G100 same as Headlight
Left Turnsignal - G105 same as Headlight

Check for proper wiring on the right Front Park/Turn Lamp if changes were made recently. Brown comes from Headlamp Switch (Park), black is Ground - brown sometimes looks like black due to dirt and grease.

Multifunctionswitch = "Multitroubleswitch", if it starts to fail here and there like mine does, rewiring to additional automotiv switches, mounted into the dashboard, could be the cheap solution.
