Depending on year, problem could be 2nd fan switch and/or fan timer module.

 

its 95 sorry

 

Problem: The fan runs continuously (longer than 19-minutes) when the key is removed. The symptom is a dead battery. The fan turns off only when the ignition is turn off then on. 99% chance the fan timer is bad. Usually happens to the 90-93 Accords.

Solution: The reasonable solution is a replacement of the timer control unit. Before a replacement it would be wise to troubleshoot. When the fan does not turn off after 15 minutes swap the cooling fan relays in the engine fuse compartment with another identical relay. If the fan refuses to turn off replace the fan timer unit.

Replacement: Remove the access panel on the driver's kick panel and search for a box way in there the size of two cigarette packs with 8-terminals. The 86-89 Accord fan timer unit is located under the passenger seat. Unbolt the unit and swap it with a new one.

 

Follow the top radiator hose back to the engine, there is a temp sensor there; when the fans are running after shut down unplug that sensor to see if the fans turn off.
If the fans shut off replace that sensor.

 

thanx i hope this works
