Hi,
I have a Toyota Hilux 2011 4 cyl. turbo diesel 4WD Crew Cab with an A/C that is working intermittently. Need advice on if the thermistor is the problem or is it something else.
When the car is started and the A/C turned on, the blower works perfectly, the A/C begins to cool, and I can drive. It is when I am driving say in traffic or getting stopped at a traffic light, the A/C starts to blow warm air. If I am on a highway, it works continuously without any problem. when in traffic and it is giving trouble, I can using the temperature setting switch and rotate from full cool on to the off position/lowest possible cooling (turn it anti-clockwise fully). after a few minutes if I turn the switch to full cool (turn clockwise fully) the A/C starts to work again.
Can anyone tell me what the most likely cause for this problem is? I have been told that it is the thermistor that needs replacement and am resisting this as it requires the dismantling of the dashboard to get at it.
thanks
Stuart

Re: Toyota Hilux
When you lose cooling, are the aux fans working? Is the compressor clutch engaged?
Re: Toyota Hilux
Or if this vehicle has a fan clutch and not electric condenser/radiator fans, would sound like a fan clutch issue.Dougflas wrote:When you lose cooling, are the aux fans working? Is the compressor clutch engaged?
I think Dougflas is on the right track by figuring that there is not sufficient air flow over the condenser and engine.
