Describe your problem. Have a 1999 ford windstar and the vehicle won't shift into gear, stuck in park. Yes, brake lights work.
Do you
have the same problem?
Yes
No

It sounds like the shift lock solenoid is out or you have a fuse that needs replacing. Here is a guide and some diagrams (below) to help you get the problem fixed.

There are diagrams below!

WINDSTAR
Verify customer complaint. Visually inspect the following components of the shift lock system:

Mechanical Components
Shift lever assembly for damage or misadjustment.
Ignition or Brake Pedal Position (BPP) switch for damage or misadjustment.
Electrical Components
Fuses No. 10 or 11 (10-amp).
Loose or damaged connections.
Brake Pedal Position (BPP) switch connections.
Wiring harness.

1. Check Brakelight Operation
Depress brake pedal. If brakelights illuminate, go to step 7 . If brakelights do not illuminate, go
to next step.

2. Check Fuse No. 11 (10-Amp)
Check fuse No. 11 (10-amp), located in fuse panel. See WIRING DIAGRAMS . If fuse is
blown, go to next step. If fuse is okay, go to step 4 .

3. Check Circuit No. 10 For Short To Ground
Disconnect BPP switch 2-pin connector. Using DVOM, measure resistance between BPP
switch harness connector terminal No. 1 (Light Green/Red wire) and ground. If resistance is
NOTE: See appropriate wiring diagram to diagnose electrical circuits and
identify fuses and circuit numbers. See WIRING DIAGRAMS .more 10 k/ohms, go to next step. If resistance is 10 k/ohms or less, repair Light Green/Red
wire between fuse No. 11 and BPP switch for short to ground. Reconnect all connectors and
retest system.

4. Check Circuit No. 10 For Open
Using DVOM, measure resistance between fuse No. 11 output terminal and BPP switch
harness connector terminal No. 1 (Light Green/Red wire). If resistance is 5 ohms or less, go to
next step. If resistance is more than 5 ohms, repair open in Light Green/Red wire between fuse
No. 11 and BPP switch. Reconnect all connectors and retest system.

5. Check BPP Switch
Using DVOM, measure and record resistance between BPP switch connector terminals. Apply
brakes and recheck resistance. Resistance should be more than 10 k/ohms without brake pedal
applied and 5 ohms or less with brake pedal applied. If switch resistance is as specified, go to
next step. If switch resistance is not as specified, replace BPP switch and retest system.

6. Check Circuit No. 810 For Short To Ground
Disconnect shift lock actuator 3-pin connector. Using DVOM, measure resistance between
shift lock actuator harness connector terminal No. 1 (Red/Light Green wire) and ground. If
resistance is more than 10 k/ohms, go to next step. If resistance is 10 k/ohms or less, repair
short to ground in Red/Light Green wire between BPP switch connector and shift lock actuator
connector. Reconnect all connectors and retest system.

7. Check Circuit No. 810 For Open
Using DVOM, measure resistance between BPP switch harness connector terminal No. 2
(Red/Light Green wire) and shift lock actuator harness connector terminal No. 1 (Red/Light
Green wire). If resistance is 5 ohms or less, go to next step. If resistance is more than 5 ohms,
repair open in Red/Light Green wire between BPP switch connector and shift lock actuator
connector. Reconnect all connectors and retest system.

8. Check Circuit No. 1040 For Voltage
Turn ignition on. Using DVOM, measure voltage between shift lock actuator harness
connector terminal No. 3 (Red/Black wire) and ground. If battery voltage is not present, go to
next step. If battery voltage is present, go to step 12 .

9. Check Fuse No. 10 (10-Amp)
Turn ignition off. Remove and check fuse No. 10 (10-amp). See WIRING DIAGRAMS . If
fuse is blown, go to next step. If fuse is okay, go to step 11 .

10. Check Circuit No. 1040 For Short To Ground
Using DVOM, measure resistance between shift lock actuator connector terminal No. 3
(Red/Black wire) and ground. If resistance is more than 10 k/ohms, go to next step. If
resistance is 10 k/ohms or less, repair short to ground in Red/Black wire between fuse No. 10
and shift lock actuator connector. Reconnect all connectors and retest system.

11. Check Circuit No. 1040 For Open
Using DVOM, measure resistance between fuse No. 10 output terminal and shift lock actuator
harness connector terminal No. 3 (Red/Black wire). If resistance is 5 ohms or less, go to next
step. If resistance is more than 5 ohms, repair open in Red/Black wire between fuse No. 10 and
shift lock actuator connector. Reconnect all connectors and retest system.

12. Check Circuit No. 57 For Open
Using DVOM, measure resistance between shift lock actuator harness connector terminal No.
2 (Black wire) and ground. If resistance is 5 ohms or less, replace shift lock actuator.
Reconnect all connectors and retest system. If resistance is more than 5 ohms, repair open in
Black wire between shift lock actuator connector and ground.

WARNING: Deactivate air bag system before performing any service

Please let us know what you find. I'm interested to see what it is.
