my car was sitting for a while about 4 months...
now the fan stays on constantly...without shutting off...can any one tell me what the problem is?

its a 1997 Z28.

Thnaks.

 

Is the SES light on? The fans will stay on when it is.

 

Im seeing these cars fuse/relay panels under the hood be rusted out more and more. take a look inside the fuse/relay center under the hood for green/chalky stuff. also, you could try to replace the relay. maybe its just bad.

 

Yes the SES light is on....the car is not overheating but them fans wont shut off, also besides the SES light being on, the check gauges light is on as well. I did a scan and i got a "misfire" code. Thats all it says no more details.

Also, on the highway runs fine...but when sitting at a stop light, the engine starts shaking...

oh and the oil pressure gauge is low...even though it has oil.

please help me as this is my DD.

Thanks to all.

 

Like I said, the fans will be on if the SES is. Fix what is causing the SES and the fans will go off. Post the exact trouble code, so you can get better help.

Your oil pressure is low causing the check gauges light to come on (is it only low at idle?). If it is truly that low, continued driving will eventually ruin the engine. It could be that the oil pressure sensor is not reporting the correct pressure and might need to be replaced.
