Where is the VCRM (Variable Control Relay Module) at on my car listed above? And also if possible could you send me a picture or a link to see its location. I'm not sure but it might be called VLCM (Variable Load Control Module) My cooling isn't working right.

Hello, I'm Danny.

Here is the information you requested. I've attached a picture below of its location. It's on the passenger side in the under hood area. I've circled in red. Let me know if you have any further questions on this issue. Here are the cooling fan wiring diagrams so you can see how the system works. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed. Hope this helps and thanks for using 2CarPros.

Thank you so much. That's where I thought it was at. I found that same diagram also. And thought it was the right one. Thank you so much for confirming that it was. Now I hope by changing it that it's the reason my fan doesn't kick on. Thank you once again.

Hello again.

That module has to do with the air ride system. Didn't your question say you're having a problem with the cooling fans? That will not fix a cooling fan problem. That is related to the air ride system. Are you sure you're not looking for the coolant temperature sensor that controls the fans? Please let me know before you buy something your not sure about. What is the symptom? Hope this helps and thanks again for using 2CarPros.

Can you please start the car and turn the A/C on for 2 minutes the fan should come on. If not lets test the fan motor 9 times out of 10 the motor goes out. Here is a guide:

and

Check for power and ground at the motor. Please run down these guides and report back.

Hello again.

Regardless of the A/C system not working properly the fan should always turn on when the system is activated. When you turn the A/C function on at the dashboard does the fan under hood at the radiator turn on? Let me know. Hope this helps and thanks again for using 2CarPros.
