the fuel pump is located on top of the fuel tank.

Helm.Com for factory manual--not cheap Any thing other than OEM will not be your car exactly

its inside gas tank

you need a new thermostat

if the signal lights work then the wiring and socket and obviously the bulbs are good which leaves the brake light switch or wiring at the brake switch is bad.

In spite of what Firestone did it still sounds like you have a defective speed sensor. Other people have also had this problem and it was solved by replacing the speed sensor. I hope it resolves your problem.

Many possible causes. Leak can be when you drive, but not show on your driveway. The heater could be leaking into the passenger area, though you'd likely smell the "maple syrup" smell of anti-freeze. It's also possible that you have a head gasket leak into the coolant, causing the overheating, and blowing some of your coolant out. Get a compression test on the cooling system, and a compression check on the cylinders.

posible cloged heater core

evap control system

you have a bar blower resistor

check the wire is connected to fuse panle

Have you tried asking them to just flush the system, as well as reverse flush? Sometimes that will clean it out enough to get you where it needs to be for now. If not, I'd try that, at another shop, obviously, if for no other reason, a second opinion. Try one that specializes in radiators if there is one in your area. If no luck, and your handy at all, I can tell you what I did to clean core out a few times that worked pretty well for me, and only cost me about $20-$30, and a little time. Let me know if your up to it, but I'd gamble the cost of a flush, and my method, before I'd pay $100's of dollars for new core.

May need a new window regulator installed.

this is your fuel level sensor is having low input voltage try cleaning the connector that plugs into it this could be corroded/dirty contacts causing this try as much as you can to get it clean if its needed if this does not work the sensors shot
