Ok well I have a '95 Camaro RS 3.4l A/T. Since I got it, its been getting hot. I was told this was normal so I didn't really worry about it. While sitting at a light or in a drive thru, the temp gauge almost hits the top. While doing 45+ mph it stays between the 1/4 and 1/2 mark. Yesterday though, it started getting worse. In the morning on my way to work, while on the freeway, the gauge hit the top temp and didn't go down. I checked the fan and its not coming on at all so I tried reseatching it online as much as I could.

This morning on my way to work I stopped and picked up a new fan relay, ect sensor, and fan temp switch. I was able to locate the two, or so I thought. The ect sensor is under the plenum on the top of the engine and the fan temp switch is to the right of it but down on the side.

I read online somewhere saying that the A/C on should turn the fan on, well mine doesn't come on still. I also read that pulling the ect plug would engage the fan so I did that and the fan did come on at full blast. So that means the fan motor isn't blown. Then I read that unplugging the fan temp switch and grounding it (its 1 wire and the ect is 2 wire) that the fan would also engage, but it didn't. What I did notice is that when it was unplugged, the gauge on the dash wasn't reading the temp. So does this mean thats not the fan switch or that it is but it also tells the gauge the temp?

Water/coolant in the radiator does go down so Im assuming thats just evaporation and its means that water is flowing into the engine. So the water pump must be working right? As well as the thermostat? Also, if the 1 wire sensor I found is for the gauge only, not the fan switch, then where would the fan switch be located? I've taken some pictures to help if they're needed.

If I forgot to mention something, I'll edit this post. If you have any questions or suggestions for me, please feel free to ask/tell me. Thank you


Side Note:
I charged the A/C becuase it was empty and it seemed to blow cool but not cold air. Later I left the house and decided to use the A/C but when I did nothing came out but warm air. Does the radiator fan affect it?

If your coolant level is dipping then you've got a leak. The engine shouldn't be burning through it like that. (If you're mixing properly you'll lose a little bit, but not much) If you've got the windows down and smell coolant burning at all then that's a tell-tale sign there's a leak somewhere (even if it's not obvious).

Not sure as far as the fans engaging, but I just went through a little bit of hell finding the leak in my car and finally found it behind the water pump. (Effin' figures right? In such a hidey spot you'd never see it leaking ever) it was leaking little by little and made the system lose pressure so even though it was going into the engine, it never got to cool it before zipping out. I hate that they put those plastic connectors all over in direct contact with hot metal. It ended up being this Z shaped plastic valve, it warped into a slight S and the insides of it were cracked.

Also, the AC no longer blowing cold air could be a few things, hopefully you don't have a hole in your compressor, otherwise it'd of leaked out all the charge you just put into it.
