1) This is almost certainly the rheostat behind the knob. Very common problem. Easy to remove cluster and replace. Suggest you also do all bulbs at same time.

2) Someone has probably had this apart to fix the odometer and did not get it back together quite right. It is complicated to get all the "counters" just right. If you have not messed with one before, I would leave it.


3) Another item to fix with the cluster out. Genereally the wire breaks at a bend. You can supposedly replace the wire with monofilament fishing line, or replace the whole assembly but it is expensive. Most used ones have the same problem.

4. A good shop can do a band adjustment that can fix the flare if there is adjustment left.

5. The switch is to turn the wipers on when you press the pedal.

7. I am not sure you can get the panel off with the door shut.

9. Lots of posts and DIY's on the heater controls.
