TNS relay
 

I noticed my Car battery would die and I had to jump the car off over the weekend , everything looked and seemed fine ... tonight right before I tried to start it I heard a noise coming from under the hood ... sounded like the fan motor was on , but I popped the hood , and coming from the relay box the TNS Relay was "Buzzing" ... I pulled it out , the noise stopped , plugged it back in and the relay itself would vibrate loudly when the relay was reconnected ... I read that the TNS relay controls all the lighting , except for the headlights , but I've never seen a fuse or a relay vibrate or buzz like that WTF ?? :banghead:

Found the problem ... FIXED :)

What was it if you don't mind sharing?

Pulled all the relays and swabbed the contacts IN the relay box , and inside the relay switches themselves with alcohol ... then , disconnected the battery while I was cleaning relays to reset the ECU (just to start over) ... everything functioned fine today , but it's a 15 year old car so I guess these things will happen from time to time :(
