reading check engine light on 1994 Saturn SL2

My check engine light comes on and off, thinking its a fluid level, tried getting the codes read from autozone but they only read 1996 and beyond. Where can I go to get the codes for a 94?? I live in CT

The check engine light does not usually come on due to low fluid levels. The check engine light is telling you the engine computer is seeing a fault with one of it's sensors or a system which it controls. Check out the RepairPal encyclopedia for more information on the check engine light and what it means. You 94 Saturn system uses what is called OBD (On Board Diagnostics) I, 96 and newer are second generation which is OBD II. Some of the newer code readers will read OBD II only. You will need to find a repair shop which can read OBD I systems. The code stored in your engine computer will lead to the system which is causing the fault. Sometimes it can be difficult to isolate the cause of an intermittent fault but reading the fault codes is the first step.

It's very possible that your engine is running at a Hot temperture, make sure that you hear the cooling fan cycling, especially when the car is idling. If its not, there is a temp sensor switch on the block that activates the fan when the car reaches a certain temp, usually around 200 degrees.

I am pretty confident they have a 195 degree thermostat, if the detail matters. You should be able to find a shop that has OBD I reader. Otherwise you can pick one up cheap. I found one on Amazon Hopefully looking into that will solve your problem. I know this might come 5 years too late, but hopefully this might help someone else.
