Shorted pin 4 ans 16 on DLC and now my power lock and ulock on my 2000 Saturn SL2 is not working

From my wiring diagram power for the radio is fuse # 29 a 25amp fuse! The fuse for cig lighter also powers the DLC Pin # 16 . The DLC is the connector under the dash left of the steering wheel . This is where you would hook up a scan tool ! Are you saying by part dash lights ,that some of the dash lights are out ? Could just be some burnt out bulbs ! Was fuse # blown ? Did you cig light work before ? Could have a shorted out cig. lighter or the outlet ! To fix dash bulbs the instrument cluster would need to be pulled ! How to Replace Dashboard Lights In Depth

While the hood is open. Rn the engine with a helper operating the gas pedal and e-brake locked. Place the car in D and then R while you are watching the engine from the side. Have the helper step on the gas in each of the gears and watch what happens to the engine. If the engine jumps around,, then you have other mounts that are broken and need replacing.

Check Pin #16 on the Data Link Connector (DLC) for battery voltage. (See Diagram)

If there is no battery voltage present check the fuse marked "OBD II" in the engine compartment fuse block. It is a 10 Amp fuse. If the fuse is good, repair the circuit between the fuse and pin #16 at the DLC.
If battery voltage is present at Pin 16 at the DLC, check for ground at pin 4 on the DLC. If ground is not present, repair the ground circuit between the DLC and Ground G202 located at the left side of the dash.
HINT: the easiest way to check BOTH of these at the same time is to use paper clips plugged into pin #16 and Pin #4 and connect a light bulb between the two. If the light illuminates brightly, power and ground are both OK.
If no problem with power or ground is detected at the DLC, check the Owner's Manual for your code reader.

A/C compressor clutch relay maybe . It's located in the under hood fuse box . If you look on the bottom of the relay an see pin's 30 & 87 an locate where they plug into the fuse box an jump with a piece of wire . Just to see if clutch engages . Pin 30 should have B+ voltage .

You put the key into the lock cylinder, the lock cylinder is directly attached to the ignition switch. Both are inside the plastic boot around steering column.

Check the CIG fuse it goes directly to pin 16. It also powers the cigarette lighter. That fuse should be in the I/P fuse box.

The trailer wires are left turn, right turn, running lights(the smaller elements on both tail-lights and any side lights) and ground. Energise the corresponding lights and connect the wires accordingly. Find a good ground. A piercing test probe will find the correct wire for you if you can't track it to the bulb.

check your fuses, quite a big one considering it supplies all your locks

open the fuse box on the passenger side of the console. Check all the fuses. Also there is a fuse box under the hood I believe on the driver side. check all these fuses also. The only other thing to check if your motors are working fine, is the wiring.
