So I had my HIDs installed by a shop here locally about 2 years ago because I wasn't comfortable messing with wires. At first they worked fine no problem. Then the pass. side light wouldn't turn on. They said I got a bad relay replaced it free of charge. Now this has happened about 3-4 times within the past 2 years. They always say it's the relay, fix it and then it works great for another few months. All free of charge which is why I keep going back but now it's just frustrating.

Recently I replaced their relay (don't know the brand) with a morimoto one so the high beams work with my retrofits. I did them this time since I had something to go off of with them installed already. This was about 2 weeks ago and now the pass. headlight stopped working again all of the sudden.

Is it the relay? Is it a bad ballast possibly? Is there another problem I haven't thought of? We've been getting a TON of rain here recently and it's been very humid if that makes any kind of difference.
