Hello H-T.

I'm having a hard time troubleshooting my integra's cooling system.

When I start the car, shes warms up fairly quickly according to my cluster. The cluster stays where she's supposed to, doesn't give me any signs of over heating etc.

But, my cooling/condenser fans don't turn on at all, even if i have AC on full blast.

If I jump the fan switch off the thermostat, both fans come on. I already replaced this new from Honda.

Any ideas?

You need a new fan switch get a mishimoto fan switch.

if thats a new oem fan switch, it should be under a two year warranty (at the very least one year). go take it back and get another one.

Also, could it be that I'm not giving it enough time? I let the car idle for like 20 mins and neither fan kicked on. Could I have to wait longer? I ordered it offline.

Fans will come on when A/C is on regardless of engine temp., so if they are not you have a problem.

You did not say what the year or trim level your Integra is.

As mentioned, you may have a bad, [DOA] ECT switch, maybe not, if the temp. gauge does not go above 1/2 to 3/4 of the way, but you still have the other problem, no fans for the condensor, this is most likely a rad fan control unit problem, [bypassed for engine temp.]. 94

I have a 2000 Integra LS, but I'm running a step down harness from obd2b --> obd2a since I swapped my 96 stuff over to a newer shell.

Since I swapped everything over to a new shell, my ac lines don't have any freon in them, even though I can still turn the AC on from the climate control.

Any ideas fcm?
