Heater blower and radio stopped working

Could be a loose or dirty ground wire. Have u installed any accessories recently?

Might be a loose battery cable. Just a thought. did see other post where you stated that you've disconnected battery several times. Hope you find/found a solution.

Best place to start is the positive lead on the battery . Remove the lead and clean battery pole and terminal using sand paper until you have shiny syrfaces. Replace the lead and tighten the terminal . Check the battery for charge condition as what you describe indicates a flat battery

Usually caused by a failing dimmer wheel/rheostat.

Check your battery see if it's good. It is check alternator.

Sounds like you have a bad ground. If it is not that you must have a gremlin.

ITS THE BULBS IN THE DASH, BUT IT SOUNDS LIKE THE ALTENATOR IS GOING BAD IF ALL OTHER LIGHTS FLIKER,IF JUST THE RADIO LIGHTS ITS POSSIBLY JUST THE RADIO LIGHTS GOING OUT

Lincolns have 5year, 50000 mile warranty. Thats one advantage to buying a Lincoln. If you are not covered your problem with the blower can be a blower control switch. Its under the hood behind the engine and in the ductwork. Its about the size of a pack of cigarettes with 90% hidden. It has 2 screws and 1 electric plug.
The radio problem could be the mute or the phone setting. Warranty should cover them both. Good Luck

have the engine wire harness checked maybe a communication problem between modules.

check the power connections at the starter and under the black cover on the passenger side under the hood on the firewall.........sounds like you have a corroded power connection
