I have a couple of maintenance questions about my 1994 Ciera:

Car has the 3.1l v6 with unknown miles though I suspect somewhere around 150K (title has an odometer mark)

1. The temperature has been running around 240 up to 250 recently. I took it to shop for diagnosis and they said cooling system was functioning fine, but suspected a bad temperature sending unit. It looks to me like there are two sending units one to the ECM and one to the gauge. Anyone else been through a similar scenario? Coolant level is fine and checked frequently, engine does not seem to be heating as gauge indicates.

2. Wipers only work on high or low. Is there a pulse module for this system like newer GM vehicles?

I cannot seem to get much above 26 or 28 with the car on the highway. Any experience or suggestions?
