1992 Regal 3.1L 4 speed auto 70,000 miles
The high temp light on our Regal will not go out. Started acting up 6 months ago in the winter. It comes on as soon as the car is started and won't go out. The primary driver is my daughter so I would like to get it in proper working order. I told her just to ignore it for a while, but about a month ago it actually did overheat and left her stranded. Since then I have replaced the original radiator & hoses, coolant temp sensor, thermostat, radiator cap and low coolant sensor. The ECM gives no codes. I also pulled the ECM fuse and disconected the battery trying to get the ECM to reset to no avail. I'm thinking short somewhere but do not know where to start. It's already 100 here in Texas and I really would like to get it fixed. Thanks in advance for any ideas.
