ABS light on, 4hi low and heater failed

ABS light, on 4hi low not working , heater not working , found a couple blown fuses replaced what could cause?

 

Well, let's see...
ABS light: Bad wheel speed sensor, broken wires, other braking problems.
4WD not working: Bad actuator, bad switch, transfer case oil, broken drive line...
Heater not working: Mixing valve, fan motor, air in cooling system...
Blown fuses: Indicative of other problems.

As you can see, there are a multitude of things that COULD cause you problems. You should probably give some more information, or limp it over to your nearest mechanic and have them diagnose the problems.

 

All lights come on at same time after battery change. Wondering if there is one fuse that would cause all to quit working?

 

Here ya go, should be all of the information you need, and then some.

Did you, even for a minute, hook the battery up backwards? Because all the things you're saying are what have happened to others who flew in here looking for solutions after their battery got hooked up backwards.

 

No battery was not even for a minute hooked up backwards

 

Huh. I wonder if THAT is why none of TBM’s pics are showing lately

 

Maybe. But Bob saw it

 

That’s because he’s Bobniscient.

 

And now you can see it too
