No digital dash lights

Instead of continuing to purchase batteries and alternators, why don't you take your car to a qualified mechanic and have it properly diagnosed and repaired. It certainly would be cheaper.

I have a 2001 lincoln an when i try to set the cruise the light will flash but it will not set ?

Check the harness connection to the cluster. Will have to remove the cluster to get at it.

I'd check those fuses for voltage, when problem is ongoing. Those fuses are hot all the time, use a test lite. Did you check voltage drop on cables and wiring? Battery has a full charge and charging system is working correctly?

it could be in fact the turn signal sound since this is produced electronically by the cluster

pull the cluster and confirm its making the sound

I replaced quite a few at the dealer for similar concerns

YOU NEED A LOCK SMITH.

Did you check all the fuse?? Do you mean the whole dash is dead or just the speedometer??? if the whole cluster died i would check the fuse under the hood in the fusebox. they are different and sometimes secured to the fuse box with a bolt

Check the charging system and check it while the car and engine are hot. The alternator is starting to fail when hot. If the engine is not hot the failure will not show up. And yes I have seen this happen on many cars of all types. A lot of mechanics forget that the problem may not show up till car and alternator are hot.

Checked Every fuse in the fuse box (no small task).This includes #4 - Power point Instrument Panel, #14 - Day time running lamps (auto lamps doesn't work nor does auto lock), #27 - ignition switch run feed, #35 - Instrument Cluster, #41 - Instrument Cluster, #42 - Delayed Accessory, #45 - Ignition switch run/start feed, #102 - Door locks body security module, #103 - Ignition switch, #110 - Ignition switch, & #116 - Ignition switch. But I also check all other ones as well, they all register OK. AC panel & radio work. Turn signals work. Mileage does not work, trip computer does. So, basically, everything works except auto head-lights, auto locks, and the dash cluster (no MPH, RPM, mileage display, Fuel, Temp, Tran Temp, and Oil Pressure).

From what you just said i dont belive the mechanic checked your fuses correctly.

Check your self to confirm, But if no avial i belive the controller for your lighting may be fried.
