Engine Cooling problem
1995 Honda Accord 4 cyl Front Wheel Drive Automatic 100000 miles

I HAVE A 1995 ACCORD EX THAT HAD A BLOWN MOTOR WHEN I BOUGHT IT. I PUT A JSPEC MOTOR IN WITH NEW RADIATOR AND FANS. NEITHER FAN COMES ON WITH THE AC ON OR OFF. THE FUSE INSIDE IS GOOD AND THE COOLING FAN RELAY IS GOOD. MY REPAIR MANUAL MENTIONS OTHER RELAYS, BUT IS NOT CLEAR ON THEIR LOCATION OR HOW TO TEST THEM. HELP?

Hi riverrev,

Thank you for the donation.

I have the cooling fan schematic here for you and from here we can start with rectification.

First step would to check for power supply.
when Ac is turned on, is the compressor engaging? If the compressor does not engage, the fans would not work.

To test the fan circuit, unplug the fan switch located on the thermosat housing and use a jumper to bridge. If fan works when ignition switch is turned to ON, the circuit is ok.

THANKS FOR THE QUICK REPLY. WELL THE COMPRESSOR DOES NOT ENGAGE. I ALSO JUMPED THE PLUG AT THE THERMOSTAT AND THE FANS DID NOT COME ON.

Before performing tests, check fuses No. 4 and 8 in dash fuse box and fuses No. 15, 18, 21 and 34 in underhood fuse/relay box.

The next step is to check if the fans are in working order.

Unplug the cooling fan connectors. Apply power to the fan connectors to test if the fans are working.

With ignition switch OFF.

Remove AC fan relay. Test the white wire for battery voltage. If voltage is available, use jumper to bridge it with the terminal next to it. Condenser fan should work.

Repeat process with radiator fan relay. ( Note the position of the terminals, similar to AC fan relay) If both fans work, next to check would be the radiator fan control module, located behind the glovebox.
