Question about 1995 Ford Aerostar

1 Answer

Heasdlights stay on when switch and key are off

The dealer guesses that the headlight module has failed.
this is a canadian model so headlights are on whenever the
vehicle is running. they were dim for a while. also highbeam
and highbeam indicator not working. highbeam indicator flashes
on for a second when ignition is shut off. If I had a schematic of
the module I could probably solve the problem.

The headlight module is a well engineered electronic black box . If you have an electronics
background you can repair me you have difficulty with the
difference between an amp and a volt a replacement is available at your local dealer for
about $150.

Ny headlights dont work have to hold lever for high beams lights to work,dont know where the headlight relay is on car.

If low beams are working then the relay is fine. Sounds like the dimmer switch is bad.

Two items to check. headlight relays and body control module. Also make sure firewall and dash grounding is good. Might also be a multi-function switch internal problem (part of directional switch) You need to test or without fail, you'll change everything and the last part changed will be the one with the problem.
Get a decent manual and a test light or better, volt meter.

Car will not start when key is turned to start position Battery is at Full charge and the idiot lights come on what is the problem I think it is a faulty switch but I'm just quessing, would that be a...

Turn ON headlights and try to start car.

Headlights stay lit, no change in brightness means an open relay.
Start car in Neutral, or move gear shift in and out of Park and try to start in Park; otherwise it is the ignition relay switch or the starter solenoid.

Headlights dim slightly: Low battery charge

Headlights dim significantly or shut off completely: Battery cable connections are really dirty. Remove cables from battery and clean cable clamps and battery posts. You may not need to boost to start.

Hope this helps!

Headlights won't stay on!

This is not due to the multifunction switch (blinker switch) but a common problem with the light control module. This module is located under the driver side dash next to the OBD Reader plug. The problem inside the light control module is a $4 resistor that overheats and sometimes causes the headlights to fail after only a short period of running time. This can be replaced if you're good at soldering, or you can replace the whole module anywhere from $75-200 (junkyard to dealer)

Body Control Module - 2000 Chevy Blazer

Not sure about a body control module, there is a pcm under the hood on the pass. side that controls most everything on these, however i would check your fuses for the seat, on the 00 models the headlights do stay on all the time while driving due to daytime running lights but if they stay on after you take the key out then id check the headlight switch or sensor on the pass side dash.
