Flashing dash lights
Turn key on :
dash lights begin flashing, turn signal indicators lightup, turn parking lights on, flashing stops but turn indicators stay lit. Turn signal fail to work correctly, radio shows err, remove key all stops. Try to lock doors with fob sets off alarm. For some unknown reasons while driving all goes back to normal.
1. What causes this.
2.what will correct this?
3.where is the best place to begin?
Thanks.

Here is the schematic that you need to have a firm grip on how its all connected::
There is also a engine ground connection and chassis ground connection that you should examine G-104/108 Chassis ground on the frame inboard the of the battery. Just follow the smaller ground wire on the NEG battery cable to the frame.
G-106 is the engine ground terminal on the block above the starter.

cleaned grounds as shown, now have constant malfunction. Replaced hazard switch, no change. I noticed when parking lights are on FOB functions properly, no alarm. Parking lights off, lock doors with FOB sets off alarm.

Engine not running, dash lights flashing
100% SPOT ON RECOMMENDATION! You MUST have a battery in circuit to filter out any alternator ripple. Your charging circuit is suspect and it needs a good inspection and most likely connection cleaning/tightening.
Here is the schematic that you need to have a firm grip on how its all connected::
There is also a engine ground connection and chassis ground connection that you should examine G-104/108 Chassis ground on the frame inboard the of the battery. Just follow the smaller ground wire on the NEG battery cable to the frame.

alternator makes 14.2 v when charging, goes to 13.8 while driving.
