Under the dash on drivers side, left upper floor board, there is a connection center or box with a black plastic cover on it, remove this cover and check ALL connectors/connections! Make sure they are pushed in good and tight. This will be located in such a position that your left foot can dislodge or loosten the wire connections. ( possible!) I have had this problem on one just like this, with the same symptoms!
