Two different problems. Check the linkage between the ignition switch and the transmission interlock. Also check for a brake-light interlock - if the brake lights don't light when you press the brake pedal, the brake light switch may be the cause of that problem.

As to the fan... are we talking about the heater/AC fan or the radiator cooling fan? Either may be as simple as a blown fuse - check the fuseblock under the hood.

check for fuel rail check for spark you can hear the pump run when key is turned if know sound is heard check fuse,relay,pump. get spark roll over check for spark if no spark pull out mod take to autozone to have tested if good replace crank sensor

Yes, it is very possible that a small internal short in the starter or alternator can cause this. Sometimes the starter wires can lightly touch and cause it to lose a charge. There are a number of things that can short and cause a battery to die over an extended period time. You should probably consult a specialist because it can be difficult to track down.

power is needed to move shifter. sometimes the shifter will move if key is off? maybe? some cars have a slot or a way to move shifter if lock doesnt work. Owners manual handy?

I HAD A 98 MYSTIQUE OR SHOULD I SAY (MISTAKE).MY HEAT GAUGE , GAS GAUGE , AND SPEEDOMETER WORKED WHEN THEY WANTED TO . NEVER DID FIGURE IT OUT AFTER 3 YEARS. DID FIX MY PROBLEM WITH THE CAR HOWEVER ( I SOLD IT !) THERE AN ELECTRICAL NIGHTMARE.

a vacuum leak on the engine somewhere can cause this symptom

I had a similar problem with my 98 mystique when i bought it used. I had no overdrive and was lucky to find a honest transmission shop that found the problem. In my case the overdrive was unplugged. They plugged it back in,cleared the computer and changed my tranny fluid and i was good to go. You should be revving about 2400rpm at 65mph. The other thing you can check is to make sure that the wires that go from the overdrive button are not broken off or coroded.
