DIY Repair the Blinkers in a Cadillac SRX

The blinkers are an important component of the overall safety on your Cadillac SRX. If they begin to malfunction, they should be repaired as soon as possible. There are three possible reasons for a Cadillac SRX's blinkers failing. The fuse may have broken, the bulb may have burned out, or the electrical connectors may have simply come loose.


1.Open the hood, and locate the under-hood fuse box. Remove the cover and locate the turn signal fuse. It is labeled "LH/POS/PRK LAMP." If the fuse is blown, pull it out with your fingers. A fuse is blown if the metal inside of the fuse is broken and no longer in one solid piece. Place a replacement fuse that is rated the same as the blown one into the fuse box and reattach the cover. Close the hood. If the fuse was not blown, you may need to replace the bulb.
2. Place the jack under the vehicle. Make sure to place the jack under the side on which you will be replacing the blinker.
3. Use the wheel-wrench to loosen the nut covers from the wheel. Do not remove them. Use the jack to raise the vehicle to a level at which you can remove the tire. Use the wheel-wrench to remove the cover of the wheel, and loosen the wheel nuts. Remove the nuts and the tire from the SRX.
4. Remove the four bolts holding the access cover to the wheel well, and pull the cover off the vehicle. Reach into the access area, and locate the electrical connector connected to the rear of the assembly. Pull on it. If it comes out or is loose, securely plug it in. Test the blinkers. If they are still malfunctioning, the bulb may be the problem.
5. Remove the blinker bulb by twisting it counterclockwise. Install the replacement 3157 bulb by twisting it clockwise. Place the access cover back onto the wheel well, and reattach the four bolts.
6. Reattach the tire and wheel nuts, and lower the vehicle. Reinstall the wheel cover and nut covers. Test the blinkers.
