I am trying to fix a couple of things at the moment including the driverside key cylinder because it doesnt unlock or lock the door and i dont know how many screws i should remove to get to the linkage because after removing the door panel i was unable to see the cylinder but i could see the wire connecting to the inside lock. Also, when dealing with the radio connection, some of the wires are moved from the plug and the front speakers located on the door are gone. Where can I buy new ones? And last but not least. Sometimes my blinkers and brights will work, sometime they wont. Is it the fuse or the wiring and how do I eliminate one of those possibilities? Thanks all for any and all suggestions/help.
