Customer Question

Hi my crv overheats with the airco on but only in traffic. When moving the airco colds and works good. If the airco is not on it doesn't overheat.

The CRV uses a dual speed cooling fan to keep the vehicle from over heating. If the refrigerant level in the AC system is too low, the dual speed fan will never kick on to high speed. So as unusual as it sounds, the engine is overheating because the AC doesn't have enough refrigerant. Low refrigerant would also be causing the AC to stop working when at idle.

Hi Jared,Sorry my laptop was down for a bit.
The coolant level in the jeep is great. I checked it out at home for myself, and the fans do not come on at all. I changed the fuse and it worked great for about 35 minutes and it started overheating again

To clarify, is this a Jeep or a Honda CRV?

Also, the level of the AC refrigerant, not the coolant will affect the fan operation- if it's a CRV.

When it was overheating were the fans on or off?

i have a 2010 Honda CRV. I'm sorry I used the wrong word. The (free on) AC refrigerant level is good if its the same thing. When I checked it none of the fans were coming on at all. AC on or off the fans didn't come on

What pressure does the high side AC line reach?

Have you replaced the AC control relay? It could be heating up and not working.
