Hi i have a 2010 i30 Wagon and for the past few months i have had a very loud buzzing sound coming from my drivers side rear door actuator whenever the car is locked (either from remote locking or HALO). The door lock still functions 100% but the sound is very loud and its about time i did something about it. Hyundai quoted me over $600 to replace it, with something like $350 for new actuator plus 2 hours labour from memory. I decided that $350 was too much and sourced one from a wreckers online for $65..
1. did i do the right thing in buying a new lock or is there an easier fix than replacement
2. do i attempt to DIY it (am moderately okay when it comes to this stuff) or do i take it to and auto-electrician/Hyundai
3. If i go the DIY route can someone help me with how to replace the door lock actuator (interactions, youtube etc)
Could not find much in regards to this
Thanks in advance
