Can't get pitman arm puller
You need to remove the bolts to the steering box and the one on the steering shaft and the power steering hoses, It's not that hard, but you now can do it yourself, just remember to mark the steering wheel shaft so the wheel is straight, (nail polish works great)
Waterpump
depending on the engine, it's a level 2 or 3 job. You'll need a spanner wrench set to take the fan off and a serpentine belt tool for the belt. The rest is just bolts holding it in place. Make sure to drain the radiator and save any coolant that can be reused. Then have a catch pan under the water pump area for the extra coolant run-off
Headlight problems
Hi. That sounds like the Low/high beam switch is malfunctioning and in need of replacement. I believe this because the headlights will not come on no matter which power source is attempting to activate them. Clearly, they are not getting power. Since the high-beam indicator light is functioning and indicating HIGH BEAM it IS getting power, There is no further interruptions in that circuit, save the fuse. IF the fuse is good,.. tested good.... Then the switch is bad, if the fuse is bad... replace it. If this doesn't solve the problem You have blown all your headlights simultaneously, or lost all the connectors to the headlights all at once, or possible got so unlucky as to lose all connectivity to just the headlights magically. I'd bet the fuse if I didn't believe that you would have checked that before posting the question here, and that doesn't account for the indicator to be stuck, so.... This pretty much leaves the switch ol buddy, sorry.

The
following are the general instructions on the start of diagnosing any
electronically controlled engine or transmission problem.
The
engine and the automatic transmission (transmission control is
only for automatics, engine is still computer controlled no matter
the transmission type) in this vehicle are computer controlled and in
most cases when a fault occurs a fault code is stored in the memory
of the computer control module. There are exception to this, such as
the Mass Airflow Meter and fuel pressure problems. What must be done
is to have all the basic testing done such as a scan of the system
for fault codes as well as a check with a live data scanner tool for
engine functions that are not within range of normal, a trained
technician is required to know what is correct and what isn't, then
based on careful diagnostics done from a factory repair manual the
correct part is replaced or the wiring repaired or the computer
replaced (known as the PCM or ECM,ECU), which is very rarely the
problem. Other basic checks must be done as well such as mechanical
problems with the engine as well as engine state of tune and mileage
on the engine. The transmission can have mechanical issues as well
such as no gear engagement at all or a failed pump or other pressure
related problems. Also engine mechanical problems can and do cause
many drive-ability related problem such as rough idle and other
symptoms.
