Ok so I have had everything that you have had happen and then some so I will tell you what you need to do. First off I would say buy new headlight set to go with your fog light set, although this is not necessary I would suggest starting new since they are only like $45 for a new kit. Second is don't be cheap and buy the $8 relay harness for both your headlights and fog light, it saves a lot of headaches and will make your driver side fog light come back on. Third is when you get the relays take the actual relay part off and put di-electric grease on the pins and then take some silicone and seal the relay to the piece it connects too. This will keep it from corroding And after all that on all of your connections put some di-electric grease on them and DO NOT seal them with electrical tape, no matter how good you think they are sealed water will get in and the tape will keep it in. Do this and your problems will be solved
