1) Does anyone know how to change the low beam bulb on my cherokee?
It was a pain in the ass to change the high bulbs, but I did it.
The driverside was ok, but the passengerside high beam was hard. I wound up loosening the battery tie down to slide the battery back a little, and it was still hard.

I can't see it possible to replace the low beams without removing the actual headlights.

2) Currently I'm averaging about 13MPG
I know that's a little low for a I-6 so I replaced the air filter, plugs and wires.
Any other options?

Thanks

You need to remove the headlamp housing.
What type of driving - city, highway, mixed?
The 4.0 liter 6 doesn't have plug wires. What wires did you replace?

City and highway driving mixed.

I plan to replace the plugs today, per request from a mechanic.

obviously, I need to get another opinion from another mechanic...LOL
