There is an electrical problem with the switch or wiring. Have it checked out/

PCM, Relays, Power locks, wiring
In a Honda Integra, you can convert manual locks to power locks. You can either purchase a kit and do all the wiring yourself, or you can purchase doors from a junk yard and redo the kit. By purchasing doors, the wiring is already set up.
re word the question
The relay switch for the locks on a 99 Chevy Suburban is located under the driver-side dashboard.

Pick up a "Haynes automotive repair manual" at any local auto parts store (AutoZone, Advanced Auto Parts, Etc.). They have wiring diagrams in the back of the book. Should cost about $15.
To repair the wiring on the trucks door locks, you will have to find the problem first. Check all of the wires connectors for loose or bad connections, and look for any places in the wiring where the insulation has worn through.
Wrong kinda locks. Locks need to be upright.
Call a locks-smith.
Fuse diagrams are in the Owners Manual - which are freely available for convenient download (See "Related Questions" below)Since both of the door locks and window switches are in the same panel, and share a wiring harness, I would suggest looking at the switch connectors and door wiring.See "Related Questions" below for more
Could be fuse. Can also be the switches. Does it fail on both doors or just on one side? The next common problem (difficult to repair) is the wiring from the front of the car has broken where it goes from the frame of the truck into the door. If the ground wire breaks inside this loom you will have the same problem. Get a good wiring diagram and trace it out if possible before tearing into the door(s).
You take it to an auto shop and have them do it
I would not see any way of this working. Completely two different set-ups. You have the old Sportvan and are wanting to use parts from an Express van. To say nothing of the wiring, switches & relays to convert to power windows and locks with the right parts.
It is behind the back door and have a switch.
Check your fuses.
First check the fuse. Second check the switch. Same goes with power windows. A weak motor will melt a switch. If that fails ,connect a 12v power supply strait to the door in question.
If the locks and rear window hatch on a 1998 Chevy Blazer lock and unlock by themselves, there is probably a problem with the fuse or a short somewhere. The locks are supposed to lock when the vehicle gets put in gear. Perhaps the system that tells the locks when to lock is not working properly.
Remove the fuse or the relay.
Locks up the torque converter.
