To check the headlight module on a Mercury Capri, first, ensure the vehicle is turned off and the battery is disconnected for safety. Inspect the module for any visible signs of damage, such as corrosion or burnt connections. You can then use a multimeter to test for continuity and voltage at the module's pins when the headlights are activated. If the module fails to show proper readings or you notice persistent issues with the headlights, it may need to be replaced.
If the headlights on your 1991 Mercury Capri won't go down, it could be due to a faulty headlight motor, a blown fuse, or issues with the headlight switch. First, check the fuse related to the headlight system. If the fuse is fine, listen for any sounds when you try to retract the headlights; if you don’t hear anything, the motor may need replacing. Additionally, ensure the headlight switch is functioning correctly and not stuck in the "up" position.
Either your headlight is burned out or you have a broken wire. You can check it out with a volt meter.
Check circut breaker, relay under ingition module cover.
Check fuse Check operation of door switches Check operation of headlight switch
It sounds like there may be an issue with the headlight motor or mechanism. Check for any obstructions or damage that may be preventing the headlights from opening correctly. You may need to have a mechanic inspect and potentially repair the headlight system.
Just a suggestion Check the flywheel
It is behind the drivers side headlight, right next to the fuse box. The name for it is engine ECM. There will be another box directly behind the headlight, that is the transmission control module, or TCM. Check out dodgeintrepid.net for tons of info on these cars.
check on eBay for a power window motor. from what i have heard its only 1991 -1994 mercery capri only
Check and see if your accelerator cable is bent and not straight. Apply a "splint" to fix
What year? check the ignition module. see manual
The 1991 Mercury Capri has one fuse dedicated to the turn signals, which is typically located in the fuse box. It's essential to check the owner's manual for the exact location and amperage of the fuse, as this can vary. If the turn signals are not functioning, inspecting this fuse is a good first step in troubleshooting the issue.
If the bulb is not the issue, it could be a problem with the wiring connection to the right headlight, a faulty headlight socket, or a problem with the headlight control module. It's recommended to check these components or have a professional mechanic diagnose and repair the issue.
