Quite possibly a fuse or relay for the interior cabin fan (heat and cool) has failed. Search for "location of fuses for 2007 corolla" to find out where they're located, and to find a diagram. Once you've identified the fuse/relay, try replacing it. If the fan has failed, though, it might blow out again and you'll have to replace the fan motor (which is usually a TRULY pita job). Before doing that, however, make sure that the rest of the A/C system (compressor, electric radiator fans, etc.) is working properly.
First I would check the fuses and relay. Second I would remove the interior door panel and check the connector pins on the motor to the window. Should that not work, you can disconnect the motor and force crank the window up. Although it sounds like a fuse/relay issue as they seem to be the only items not working. Let me know.
Hi:
Where is the fuse located for the blower fan on an '86 Corolla sedan? Help appreciated...can you reply via email, to [email protected] ? Name is Neil Thanks...
Sounds like you have air trapped in the heater core when you flushed the heater core. loosen the upper most heater core hose and run the engine untill coolant seeps out. Wait until the coolant has reached running temperature.
1st your fan motor may be going or something has fallen in the vents you will need to gain access for that, or it might be YOU MAY HAVE AIR BLOCK, OR BLOCKED HEATER MATRIX, CHECK FIRST CHECK THE HEIGHT OF THE HEATER MATRIX IN THE CAB , IF ITS HIGHER THAN THE FILLER/EXPANSION TANK. THEN COULD BE AN AIR LOCK, LOOK FOR THE HIGHEST PIPE AND SEE IF THERE IS A BLEED VALVE, IF NOT TAKE BOTH PIPES OFF THE MATRIX FEEDS (TWO PIPES GOING FROM ENGINE BAY TO INSIDE OF CAR, AND FLUSH OUT WITH HOSE TO SEE IF IT IS BLOCKED, AND RECONNECT LOWEST PIPE FIRST AND FILL SYSTYM TILL WATER APPEAR FROM TOP AND RECONNECT RUN MOTOR, AND KEEP TOPIN UP, YOU CAN BY A COOLENT FLUSH SOLUTION TO CLEAN THE SYSTYM OUT
one fuse, but your have a resistor block somehwere under the glovebox area, some of the resistance wires on the block may be damaged or gone. this is a pretty common problem. pull the block out and look at it if all the wires are connected, then your problem is somewhere else, like the switch in the dash.
the fuse would be located under the dash on the drivers side... other things to check would be the resister block on the duct work near the fan motor. it's held in by two or three screws... one other thing to try is to turn the fan on then tap it gently with a hammer... if it comes on it's likely the fan needs to be replaced.

Please take a moment to rate this solution.. thanks
if the fan does'nt come on at any speed have the fan checked if fan is good check the switch if on good replace fan switch located inside there is also a regulator under dash behind the glove box if the fuse's,motor & switch are all good this regulator the last comp. in the heater circut or you have a broken wire. hope this is helpful
Hi.
A number of possibilities...
1/ lack of coolant in system,
2/ coolant supply to interior heater blocked / controls jammed,
3/ failing thermostat switch to engine fan
4/ failing water pump
#2 may be separate problem and I would check out #3 - after #1, of course!
Hope this helps - if not hold the rating and add a comment below. Cheers, D.
