Question about 1990 Honda Accord
The fan stop working all together its cold out so no AC. Started to get hot, so where do i start
I would start by checking the fuse. You will have to look up the location for that model because I am not sure. Next, I would check power at the fan connector. If you have 12 volts (or close to that) then the fan motor is most likely bad. If no voltage and the fuse is good, you need to troubleshoot the fan switch.

SOURCE: engine gets hot
There are 3 potential problems:
--faulty thermostat. If it is not opening all the way by the time the engine reaches 160-180 deg F...then coolant is not flowing enough.
--partially blocked radiator caused by build up of rust over the years if never flushed as regular maintenance.
--Insufficient coolant to water ratio. Should be at least 30% or more coolant in the radiator.
--Or combination of above.
Hope this helps.

It is (in order of likeliness) either a fuse, the resistor (located in the airbox near the fan for cooling purposes, that resistor gets HOT!), the fan motor itself, the control switch, or, less than likely, wiring issues.
It can be quite a job to get in the airbox for the resistor and the motor as you probably have to take half the dash and trim out in order to get to the airbox...

Your AC system is supposed to shut down if the engine is hot, as a safety device-make sure when the ac is running , the radiator fan is blowing-it may not be, caused by either a bad relay, blown fuse or a bad fan motor. Make sure your antifreeze is fully up to level, and if you haven't done it in the past 2 or 3 years, get the cooling system serviced with a new thermostat-cheap insurance, you do NOT want to overheat that aluminum engine, because if you do, it will be toast.
