    Relay for radiator fan is relay No. 1. It is located in the fuse and relay box in the engine bay area.

    Take out the fan relay, switch ignition ON and see if radiator fan stops. If the fan stops the relay is faulty. If the fan does not stop, there may be a short circuit in the wiring.

How to fix fan cold/hot system toyota avensis 2007 2.0 lt


Perhaps the Avensis has a brittle cable like in the Highlander.
Please see
http://www.tundrasolutions.com/forums/highlander/32217-heater-quit-sort-of/
It's usually broken solder joints on a cable behind, and feeding, the temperature knob.
I repaired my 2002 Highlander yesterday thanks to this site.

How do I disconnect heater for 2004 Toyota Highlander?


bypass the heater core. 2 small hoses run from the firewall to different locations on the engine (one should be the thermostat housing. dissconnect one hose from fire wall end, and reconnect it to where the opposite end of the other hose is located, creating a loop that does not include the heater core. The remaining hose (one end still attached to the heater core at the fire wall) should be connected to the opposite connection at the fire wall so it can be re-engaged next winter.

Actual problem seems to be the heat damper valve, which restricts water flow into the heater core, easiest fix is reattach the actuating cable to the valve arm (if this was detached) most costly is replace valve assemble/heater core assembly....

How do I disconnect the heater to my 2004 Toyota Highlander


If your problem is constant heat and you want to turn off the tap off but cannot then find the hoses to and from the heater and simply connect then together. Price --1 connector , 2 hose clips and a bit of time.

hi there..... if you have a abs light on this means there is a problem
with the abs. and its usually a wheel sensor. but could be one of several problems. the only way to remove the light is to repair the fault
that is something that's isn't within the scope of the diy motorist.
and would require a visit to the professionals. only then will the light be
reset. and go out.

yes the O2 heater in the sensor will make the CEL come on because the computer is not receiving proper signal from the sensor.
