I have a '91 CRX.

The fan should not stay on all the time. The mechanical temperature switch (that I described above) going out is the most probable cause for what is happening. The fan should only come on when it gets a little past halfway ont the temp gauge, then shut off once if falls below halfway. In a way, its good luck for it to fail in the always-on way, as opposed to failing in the never-on way.

If that switch hasn't been replaced as far as you know, then its well overdue. Try it first, and feel free to contact me if you need more details or get in a tight spot. Good Luck!

PS: Fixing it might reveal other problems, once the rest of the cooling system starts behaving properly without the constant help from the fan... but we'll get to that when or if it happens.
