Ok so I just finished fixing the no start problem I had, so I was driving around to see if any other issues came up. Drove fine sat in the car for a minute then it over heated. The hose that is right under the distributor that goes to the heater core busted. I replaced the hose the car still overhears and the fans won't come on even if I turn the ac on they still won't come on, the upper radiator hose and where it connects to the engine was bone dry , what do u guys think?

Crack the bleeder valve open on the thermostat housing to make sure there isn't an air bubble preventing coolant from getting to the thermostat.

I pulled the t stat out to get coolant flowing so I could get home, through the t stat in boiling water and it checks out good, I switched the cooling fan relay with the power window relay power windows work fine fans still won't come on, when I pull the relay out and jump the fuse box where the relay goes the fan cuts on

Did the fan run after pulling out the thermostat? May be a bad fan switch.

paysos

No the fan did not run where would the fan switch b located

brianb242

there is two fan switches, one is on the upper rad hose, the other is on the thermostat housing, there a green plug.

If I jump both locations with the key on the fans should come on correct?

paysos

Jumped both fan switches fan still don't come on

Check the fuses...not sure of the year so I can't give the location....

paysos

Underhood and underdash fuses look good

poorman212

Put 12v directly to the motor...which one is not coming on, drivers or pass side.

paysos

When I jump it from where the cooling fan relay goes the pass side fan comes on

poorman212

Can we take a step back....first what year is this?

So you jump thermo a, should be on the t-stat, green connector and no fans-either side?

It's a 93 accord lx automatic , yes I jumped the switch by the t stat housing with the key on and the key off and I got no response from either fan

paysos

Ok got it , I didn't connect the fan timer relay after I finished fixing the no start issue
