I have a 97 Camaro Z28. It doesn't run hot according to the gage, but the fan will stay on hours after I park the car. Any ideas on the culprit, and is it an easy fix?

 

Wow! that's weird. Do you have a switch rigged up to it? The fans are controlled by the pcm.

 

No. No switches.

 

This thread had nothing to do with the New LS1 Owners - Newbie Tech section, so I moved it here to the General Maintenance & Repairs section. Please post in the correct sections.

Thanks,

Shouldn't stay on for hours, gotta be killing the battery. Buddy of mine has his tuned to keep them on for a couple minutes after key off. Just one fan or both?

 

im guessing the relays are sticking

 

Some cars have a radiator fan turn on switch...not sure if yours does or not...

 

Well it stayed on long enough yesterday to kill my battery.

 

Are they easy to get to?

 

I have the same problem so please help out !!

 

yes, i think on the ls1 cars its on the drivers side under the hood in the fuses box! look for fan #1 and fan #2 big gray or black relays

 

Were both fans running or one?In order for both to be running, three relays would of had to stick-very unlikely.

 

Try resetting your PCM connections. Remove them and reseat. Make sure they are clean.

 

I just went and bought all three relays and put them in and nothing. My fans are still turning on. The only way to turn them off is to take out the Fuse for the Cooling fan which is a 10amp.

What can it be ??

 

in ur situation i think the blue and green wires may hav grounded! try to diagnose the issue! remove the big connector on the passenger side! the one with the J and H blue and green wires.

 

So just check to see if they are loose and grounding ???

 

if the blue and green wire, if those two wires ever ground anywhere low or high speed fan will turn on regardless of the car being started or not. so keep that in mind. maybe the wire melted someplace or the pcm is damaged. u know what i will look in my haynes manual right now for u to see what the problem it bro

 

Thank you very much!!! My car is my only car and I need it for tomorrow. Sorry ot be ignorant but, should I check the cable that connects to the fans and see it thats the problem ? Is that the cable your talking about ?

 

look at this link to giv u some examples. this is for the fan switch mod.
