Do you think the following problems could be related?

Windshield wipers work slower than normal on all settings.
Cranks over slow.
Heater is strong then not strong.


Thanks,

Seems to me like low voltage. Alternator losing power or battery has a bad cell. Start by getting them tested to begin, don't replace unless confirmed bad.

x2 - also check the connections on top of the battery inside the little black fuse panel. There are some strip fuses, the fuse with the large black cable attached is for the alternator.

I ran a charger on it for a few minutes and it started up. Let it idle to charge, if it could, it started back up right away. Came back hour later barely cranked over this time but did start. Turned it off then on again and it was fine. The battery date is 9/10 pretty new.

Meaningless. Def sounding more like a voltage problem. Get the battery and charging system tested before going any further.

Changed the battery and so far so good. The wipers are still slow must be separate issue.

Sounds like the pivots on the linkage are seizing up. They tend to dry up and corrode. You'll most likely need a new linkage. To know for sure, remove the motor/linkage assembly from the car. With the motor disconnected from the pivot arms, the linkage should pivot effortlessly.
