My father owns a 1997 Mercury Grand Marquis and he's been having a cooling problem. I figured this would be as good a place as any to find help, seeing as how the engines seem to be fairly similar to the 4.6 L powerplants in our cars. The Marquis has two cooling fans, an engine driven and an electric fan. The electric fan is not working for some reason.
We (dad and I) figured it stopped working soon after the "fantastic plastic" intake manifold had to be replaced. That was about a year ago. We have not had a major problem with overheating as we have been using the car for mainly short distance driving around town. Lately, though, we've been using the car for more prolonged driving, and the temperature gauge has been moving higher than it had ever been as far as we can remember. Two weeks ago we did some basic tests to try to weed out some causes and home in on likely culprits.
The fan itself still worked when we ran some wire straight from the battery to the power connector. We checked the fuse panels and found that the fuses and relays were still functional. We don't own a code reader and haven't rented one yet. Can anyone give some insight as to what might be wrong?
