I have noticed the radiator fan on my 1991 Daihatsu is not working, thus making the radiator overheat. What can I do to make the fan work or what is the problem?
Check the relay, thermo switch and other electrical connections and make sure there is power at the fan. It could be the fan itself if all that checks out. In that case you should be able to buy a secondhand one from a Daihatsu wrecker.
