That's because they are hidden quite well. If you look at the engine, you'll see yellow plastic prongs (?) that look like spark plugs, but hook up to the silver tubing. That's the fuel injectors. BUT, right behind the yellow plugs, are black ones. The black one is the connector to the spark plug. The plug itself sits about 4 inches down into the block of the engine. They are a real pain, and from what I can tell, you only have decent access to the first 2-4 of them, then they get too far back and start going under the dash (you'll see what I mean when you get there).

the heater bypass is quite simple, if you look at the firewall you will see two medium sized coolant lines, remove them from the firewall and link them together using a proper sized tube, you can purchase a kit at a parts store quite cheaply

I would flush the whole system with radiater flush then replace with new coolant. But make sure the heater is set to full heat when you flush it ( while driving around the block with flush in it) so the small radiater that has the hot water flowing through it gets flushed too. It may have some build up in it stopping the full flow of heated water/coolant through. If it is bad enough may need to remove and spray out the rubber hoses from the motor to the heater core, and possibly remove the heater core and hose it out to make it flow better and therefore increase the heating ability. Hope this helps.

You should check your blend door, go to the center of your dash look down towards the floor right at the bottom on the hump (tunnel area) you will see a black or same as interior color, cover it has small slits cut in it, it is held in by two expanding type plastic bolts, they do not unscrew, just pull them out, one on each side. Once removed locate the white small box with a wiring harness connected to it, a little to the right hand side. This is the stepping motor that controls the blend door. Remove the stepping motor, and reconnect the harness, look at the motor drive unit and operate the heater control knob, does the motor turn, if it does then use a mirror and look at the drive end of the blend door itself, it is probably broken. If the door is broken, this repair just got difficult, the entire dash will have to be removed to access the environmental station, once accessed there are about 10 screws that hold the top cover on the enviromental station, undo these screws and remove the top cover, then you can remove and replace the blend door. If you are not comfortable with this difficultly level in repair I suggest you seek out your favorite local shop. removing the dash is not easy, there are alot of screws, some in very difficult places to reach. Testing the motor is easy. I hope this helps, let me know.
