I currently have a 2003 Saturn lw200 2.2l and recently discovered it overheating and found that fan has not kicked on. I was conflicted and did some research and found out about troubleshooting the fan and I did and it worked but the next thing is that I replaced the engine temp sensor and still acted the same. My temp gauge fluctuates up and down and I thought it was the thermostat but still not the case at this point I don't know what it could be. I heard of the relay but I look at my relay box for the fan relay and wasn't there - there was no fan relay. I found the fan 1 and fan 2 fuse but they weren't blown. Would you guys have any idea what I could do to fix this problem for my fan to run or where I can locate the fan relay? I couldn't find it under the passenger side either. I'm left at this case thinking it's a clogged radiator but that has nothing to do with the fan. Thank you for your help and answers. If you are having the same problem don't be afraid to respond.
