2004 Mercury Mountaineer - just replaced the blower assembly after taking apart the entire dashboard - now the car starts, everything works but no power pressing on gas pedal - car is saying limp home mode

Most dashboard lights are on the tail light circuit.

Strange for blower but not unusually for compressor. The usual high or low limit switch would cut off the compressor but not the blower. Maybe check alternator and battery voltage to see if there is a voltage problem. The blower motor resistance switch is problematic but I have not heard of one acting like yours.

With a manual. Taking it apart isn't the hard part. Just start removing everything. Putting it back together. You need sequences and torque specs. Do it wrong and you will do it again.

replace the whole hub assembly with new bearing and hub kit hub must be presed apart n presed back together yo

Is the battery good in it?

You must replace the entire assembly to get the lens.

no special tools in particular just the usual or necessary tools required.. 1stly u remove the Tyre and the caliper then u'll see something like a long rod dats the bearing

check the resitor under the dashboard near fan blower motor

On a 02 Explorer you lift the hatch, remove two screws that hold the tail light assembly in and then carefully remove the entire assembly. There are guide pin at the back of the assembly, be careful not to break them. Installation is the reversal.

go to an advance or auto zone parts store if they are more they will price match
