2012 Cadillac SRX- Headlight Keeps Burning Out

This 2012 Cadillac SRX came in with the complaint that the passenger side low beam headlight keeps burning out. The customer had the halogen bulb  replaced several times before bringing it to me. In order to get a good look at what was going on the air filter housing assembly had to be removed. Disconnecting the MAF sensor and removing the harness from the top cover was the first order of business. Next the hose clamp had to be loosened and the hold down clamps had to be released.

After the top half of the air filter housing was out of the way the bottom needed to come out. It is quite a chore to lift it off of the mounting pegs and then wiggle and twist it around just right to get it out of the hole. You may be able to work around not removing this or possibly not completely removing it but I need the extra room to work and take pictures.

The cover at the rear of the headlamp assembly turns to the left and then will pull off of the headlamp assembly. Once the cover is off the bulb and harness are turned as an assemebly and removed from the lamp.

Then the connector can be removed from the bulb. Enlarging the next picture will allow you to see how badly the connector is burnt. Unfortunately the bulb was replaced several times but none of the installers bothered to replace the harness connector.

I installed a new harness connector using splicing terminals and heat shrink tubing.

The wires spliced in and the heatshrink tubing in place.

To install the bulb and connector they should be connected to each other and then installed into the lamp assembly as a combined unit. Making sure to not touch the glass portion of the bulb. Always install a new bulb when replacing the connector or the repair will not last very long. Heat damage transfers.
