Power Lock on passager side has to be flicked several times to get it to lock, Any Ideas, and are there any tricks taking that panel off that door driver side works fine. Also I was wondering what causes the headlight to turn that yellowish tint,, and any ideas how to get rid of it to bring it back to that crystal clear look,or does it need to be replaced and is it hard to replace

 

needs to be replaced... pull door panel off.. its fairly easy to do.. the headlights.. thats age.. .the plastic responding to the heat the headlights put out.. its normal.. and can be seen on alot of older cars.. even some newer ones.. theres a DIY in here on how to fix that.. it involves 2-3 hours worth of time.. sand paper.. and clear laquer.. read up on it. .cause there is a special process so you dont damage them..
