Keyless Entry/Power Door Locks on LS? help please

i was wondering if power locks come on 1991 ls because i have a keyless entry that wil allow me to unlock my car and lock it with my alarm remote. And ll of a sudden my alarm sets but my doors do not lock or unluck with it and i have to do it manual. It’s not a big deal but i just wont eveything working rght on my car. Does anyone have a clue what’s going on?

Thank You

On the 94 LS door locks are an option.

Does locking and unlocking the drivers door with the key also unlock and lock the pass. door? If so, you have power door locks, if it does not you do not have power door locks and you will need to install actuators, [power door lock motors] into the doors, then you can use the alarm as a key-less entry.:whisper:94

the keyless entry was working when i bought the car from a friend and now after the other night it doesnt work…

Is there a lock and unlock switch on the door?? If not then I’m sure there was some aftermarket actuators were installed.

OK, that helps, but then you kind of said that on your OP, I asked if locking and unlocking the drivers door with the key, also locks and unlocks the pass. door, it would have told me if it was a stock power door lock system, and if it worked the problem would be with the aftermarket alarm, if they are not stock power door locks, [no power door lock switches on the doors as I’m Trying mentions] then they will be aftermarket, and there will be a pair of SPDT relays connected to the actuators, [possible built into alarm] and the relays have probably lost their power or ground, maybe a blown fuse.

What is the make and model of the alarm?:hmm:94

There is no power door lock switches. the brand is ungo but i dont know the model of it…

Then you will have to stick your head up under the dash, find the 2 actuator leads that come from the door(s) and fallow them to the relays or alarm brain.:idea: 94
