Question about 2003 Toyota Corolla

1 Answer

My air is not blowing, the ac is working because what comes out when the car is moving is cold, but the fan/blower is not going. It happens intermittenly... When it happens, i've started the car and it doesn't come on... it may come on when I'm driving or it may not... a couple of times it has come on when i've gone over small bumps, other times, it just comes slowly on. I figure it is the blower, but the only diagram I have is for an older corolla.... would the 2003 blower be set up and in the same location as on an older model? (book is for 97 to 01 i think)

Remove the glove box by removing the strut screw, then squeeze sides of glove box together the pull out glove box. look through the hole where the glove box usually sits, towards the top you will see a rectangular panel which can be removed with out tools. behind this panel is the cabin air filter. take note of the orientation of the filter before pulling it out so that you may re-install it the same way. blow out filter with compressed air or replace. You can hear if the fan is operating through the filter opening. If is not then pull the power plug off of the blower; it sits at the bottom of the air box assembly where the filter slides in. Check for power, No power? check fuse. Still no power then replace the blower relay. Yes power then replace the blower motor. if you need to replace the blower motor then remove the small shelf at the bottom of the dash; 3 plastic clips and pull forward- set it aside on the floor. 3 screws hold the blower in place- note location of plug. I would recommend replacing the AC clutch relay at this point because of a high failure rate. There is also the blower motor relay but if this goes out you loose one or more speeds but not all of them. All of these part are available from rockauto.com, very low cost.

Vents won't blow hot or cold air. Comes from defrost and feet when you put fan on.


It's the vent actuator, it moves the baffle that changes the direction of the air flow.
Here is a video of a broken vacuum hose that creates the same problem.

It could also be a failed actuator.

Not sure which fan you mean. Engine cooling fan is different from heat/air blower fan.

My ac is acting funky. my ac will blow cold air as im moving. once i stop and idle for longer than 3 or 4 minutes, something will kick on and then it will start to blow hot air. as this happens, my car...


Start by checking to make sure that the a/c condensor and radiator is not full off debris. If the condensor and radiator were full of debris it will limit the air flow from the engine cooling fan which in tern will cause a high discharge pressure on the discharge on the a/c causing poor or no cooling at idle and could also cause vehicle to overheat. Check and make sure that the cooling fan as well as the condensor fan are coming on together when the a/c is turned on if equipped with 2 fans.

The airconditioner only works in my 2006 H3 when the car is physically moving over 25 mph. If it is going slow or idling there is no air coming from the blower/fan. When it does blow it is only on a low...


There is a HVAC relay and FUSE in the under hood fuse box, have you check both of these? If the blower works on any speed, the blower is good. You say it blows on lowest speed? The blower speed resistor is mounted on the blower housing. The HIGH SPEED BLOWER RELAY is mounted on the blower motor. You may have multiple problems but check fuses first, if all is OK, then a qualified repair shop will need to check further. You do NOT need the whole A/C system replaced. If it does blow cold, thats good, you just need the blower working.
