-----Question-----
My car runs hot only if it is in traffic. If it is constantly moving it does not run hot. Can you tell me what might be the cause of this. I think the fan is not coming on is there a relay switch where I can reset it.
-----Answer-----
Low coolant can cause a variety of issues. First, once the car cools, check your coolant level. If your coolant is low, check for leaks and repair them, and then top off the coolant.
Most likely, however, your idea that the fan is not working properly is probably correct. There isn't anything you can do to reset the fan. You should check the fuses and relays required for fan operation to make sure they're okay. And you should check to see if you can operate the fans by turning on the a/c.
Since I don't know the year and model of your car, I'm unable to provide you with specific information regarding the fan circuit. If you reply with the year and model, I should be able to give you more specific information about how the fan operates.

AnswerIf neither fan comes on when you turn on the a/c (and the car isn't overheating at the time), then you definitely have a problem with the fans.
The condensor fan is powered by a pink 30A slow blow fuse-- I believe the frontmost fuse in the fuse line on the right side-- in the underhood fuse box and the radiator fan by a blue 20A slow blow fuse-- I believe in the front left corner-- in the same box. This fuses will have clear plastic covers on them through which you should be able to see the fuse element and tell whether it's broken. My diagram doesn't label the box's orientation, so it's best to look at the labels on the lid for your fuse box to be sure you're checking the correct fuses.
The condensor and radiator fan relays are also in the underhood fuse box. Each relay is controlled by the ECM, which will control the fan operation depending on the reading of the coolant temperature sensor and whether the ECM will allow a/c activation.
You can see the schematic for this system at www.hmaservice.com. You'll need to register for a free account, and the site requires Internet Explorer. You'll probably also need Adobe SVG Viewer (a free download) to be able to view the schematics.
