go back to where you spliced in the harness and check that you have not spliced a power wire to a ground wire ( only reason why fuses blow is a dead short)

Krjs This happens a lot. Especially by "10 minute " oil change dealers. Goggle your problem. There are kits available where you can "tap out" the damaged threads and install a new bolt. In the meantime if this is really urgent, got to AutoZone, Pep Boys or similar anyplace where you can get a universal rubber plug that will carry you over. You'll get thru this. Hope this helps, Bud

You have a short to ground in your rear defrost circuits unhook your rear defrost on both sides and see if the ground is eliminated at the fuse. If so it's the grid itself, if not the hot wiring is shorted going to the glass.

Many times that this happens it is the climate control panel. it is malfunctioning. However that is not always the case. Many instances the vacuum hose for the blend door becomes unattached. Re attach this hose if you find it is unplugged. If it is not those two problems it may be that your blend doors are sticking. These may not be the most accurate answers but they are common problems I have seen and repaired in the past. I would check those 3 and if no problem found contact your vehicle manufacturer.

there is a relay but if it were bad none of your locks would work. your problem is the door lock motor it is a little electric motor that actuates the lock. its also called a door lock actuator. kind of expensive and a little difficult to replace.

gas light normally means no fuel.. must add at least 1/4 tank to the vehicle..may have frozen lines or air in them..put gas in it..turn the key on and off without cranking the engine about 6-8 times to activate the fuel pump ..you should hear the pump come on for about 2-3 seconds..then try to start.. if it wont start.. need to bleed air out by opening fuel line near the top of the engine by the tbi unit..once all gas comes out.. reconnect it and try to start...dont let get below 1/4 tank in cold weather...forms ice in the tank..

unplug blower motor see if it blows then if does the resistor board is gone in it that controls the blower fan high med. low switch

Sounds like a bad ground to me, although i am no expert. i would be checkinh all connections and take it from there, a little wd40 might just solve it short term.

Could be a defective radiator cap, or a leaking head gasket.

Under hood is power distribution for engine reated. Fuse box for interior is below driver side dash.

with a glass.. like a shot glass poor half a shot into the intake. have a fire extinguisher handy and try starting it if it tries to start could be fuel pump or fuel filter

Try checking the "Main Relay" and its fuse. Hope this helps.
