I have a 2005 Toyota Sienna, and when I turn on the A/C the cooling fans mounted to the radiator are not turning on . This causes the condenser to over heat and have excessive high pressure. At this point, I am not sure if the fans turn on at all. (although I did see them cycle (at low speed) a little bit the other day) I am thinking about changing the cooling fan computer module, but are there any relays or sensors that could also be the problem? The cooling fan cpu is pretty expensive.
Kind regards,
Dave
