Power Mirrors and Power Door Locks 96 EB Bronco

[96FORDBRONCOEB]

I have a 1996 Eddie Bauer bronco that I can't figure out the following problems.

1. Power Door Locks - Do not work

2. Power Mirrors - Do not work

I have looked over the diagram for the wiring for both. The power windows on both side door panels work without any problems.

Locks - When you press unlock or lock from the door panels you can hear them click but nothing is moving at all

Mirrors - These mirrors have the red turn signal on them. And they are working fine. But the power mirrors to move them neither side works.

There is a possible fuse in the Hanyes Bronco manual (page 12-28 Chassis Electrical System/Rear Components and Accessories) that looks like an inline fuse (10A Fuse) from the Electric Motor Switch from the Mirrors and the door locks that is in a red wire that I think might be the problem. But I cannot find it anywhere.

Any help would be greatly appreciated.

Thanks

Welcome 96,

I don't think the mirrors are stock equipment. Fuse # 8 should be powering the mirrors. I don't recall the factory using any inline fuses.

The door lock problem is probably the lock solenoids. I had the same problem, had to replace both solenoids.

Good luck

6 - A/C Clutch, Diesel Aux. Fuel Selector a, Remote Keyless Entry

8 - outside mirrors, Speedometer (PSOM), etc. ARE Speedometer (PSOM) window COURTESY lamps and key left in ignition, etc. warning chime and other components on this fuse working?

if so, troubleshoot mirror ckt

12 CB - PDL, Tailgate window, etc. is TG window and other components on this fuse working?

if so, troubleshoot PDL ckt

Wiring Diagrams With Remote Keyless Entry (RKE) in a 96

=========

Mirror;

Signal mirrors (as equipped by Ford) display a supplemental turn signal through the outside rearview mirror glass surface. The signal is directed toward vehicles in adjacent traffic lanes and is not visible to the driver of the equipped vehicle.

The signal mirrors are equipped with an integrated light sensor and automatically adjust the brightness of the signal display for day and night operation. The signal is connected directly to the turn signal wiring.

yo, I had to post up because my CC conn slowed to a dead stop

PDL Pinpoint Tests

CAUTION: Do not replace parts unless test results say they should be replaced.

NOTE: Keep the front door window glass (21410) rolled down during all pinpoint tests to avoid being locked out of the vehicle.

Before proceeding with diagnosis and service of the remote entry electrical operation, check for mechanical binds in the power door lock actuators (218A42). Operate all power door lock actuators several times and check power door lock actuators operation. Also be sure the battery is fully charged.

NOTE: To lubricate linkage, use Multi-Purpose Grease Spray D7AZ-19584-AA or equivalent meeting Ford specifications ESR-M1C159-A and ESB-M1C106-B.

Spray into latch opening

It may be necessary to remove the door trim panel to lubricate the entire latch and linkage system.

Manually cycle the lock ten times

Check for interference around right latch and all linkages.

Check that battery is fully charged (if not, it may be causing the concern).

miesk5,

Thank you for all the information. I will try to give this a try this weekend and give an update after.

Thanks again!
