Door Locks Finally Fixed !!!

[Alpine003]

Eversince buying the car recently, it had bad door locks. I must've went through diagnosing everything.

-replaced the central door lock relay and that seemed to work intermittently only on the passenger lock.
-took a multimeter and measured all the wires for continuity.
-did a visual on all the connectors for corrosion.
-swapped the locking actuators
-also swapped another central door lock relay
-tried to unlock/lock using the trunk lock

Finally ended up being a driver's door lock actuator that was shorted or something that caused all the other locks and /or the central door lock relay to not work 100%. Replaced both front actuators and now everything is working.

Reason why I'm posting is that one door lock actuator can cause havoc on the entire system. Another symptom to look out for to see if door locks are on the way out, is if it appears to be "lazy" in going up and down and not "crisp".

I have a drivers door lock that could bend a key so I use the trunk. This write up gives me info I may need one day, THANKS!

Go keyless entry. It'll be the best $25 you ever spend on your car.

Update:

Ended up replacing my central lock relay 3 times and all my door locks 1 time.

After numerous troubleshooting, I found a small crack in the rubber booting connecting the door to the chassis where the wires run through. Under heavy rains, the water would seep into it and travel down to the lower kickpanel where your speaker and central door lock relay is and cause it to get wet, including the wiring.

This eventually shorted out my central door lock relay and on the 3rd replacement, also shorted out all my door locks.

I've since siliconed the rubber boot and relocated my central door lock relay from the kick panel(poor placement anyway) to under the dash.

Cliff Notes: Check your rubber boot that goes from the door to the chassis for any leaks which can damage your central lock relay/door actuators.
