97/98 ford f-150 door lock issue

The driver door lock switch inside of this truck works fine by hand, although using the alarm in which a viper 550esp is connected was wondering what problems this may have. When you lock using the remote it still try's to lock for a couple more seconds, unlock is fine, as well as the switch. Could the actuator be bad(not likely), could it be programmed for pulse locking?

thanks,

I'm not sure about the options available on the DEI unit but some other modles that I have installed has a programmed lock duration of .75 seconds, 3 seconds and double pulsed .75 seconds. Check the programming for this option on the Viper.

Will do,

Do you think this may be the problem most likely?

As always thanks Jeff!

Thanks Jeff,

I'll post the results tomorrow night.

I had the same problem once with a DEI alarm. Sound pressure, the problem should be with the alarm, programing the lock.                                      

It was kind of weird to figure out how to program the alarm's options. I mistakenly programmed the door lockoutput to be double pulsed.

I re-programmed the entire alarm still no luck! The only other thing that I can think of would be the relays for the door locks. The wires for it are Pink / YELLOW for lock negative trigger, and unlock is Pink/light green reverse polarity right? What is the layout for relay connection is this truck for the door locks? I can check this, could be a bad connection.

This is what I have for the Ford F-150 door lock systems. The year will not matter as the models did not change from 1997  - 2001

Hey Jeff,

I'msorry. Never did one of these before and now i'm face with repairing one of them. The above post will require relays right? If so is the above a 5 wire alternating? How would the relays be connected? I see the diagram for a 5 wire alternating but I don't see all the above wires being connected as the diagram. I guess that I've been faced with easier alarm installs and I want to learn to do the more difficult ones.

Thanks,

Hey Sound Pressure;

You need to go into the door for all the wires needed for the 5 wire alternating door lock relay circuit. Your best bet is to cut the wires at the switch ( so you have switch side and motor side ) and then run the 4 wires into the dash area of the truck and attach the 2 relays by the remote starter like it has pictured here: https://www.the12volt.com/doorlocks/page3.asp#5w Post your results.... it's an easy installation, believe me .... the first time is always the worst.... after that........ it's all good  !!
