hey does anybody know where the location of the electirc fan relay is on a 1991 chevy camaro rs 305 TBI. i have a chilton manual but that dosnt tell you anything. the only relays i can find are the two on the drivers side firewall under the hood. i beleive one of those are it but i'm not sure which one. also the reason i need to find this is becuase when i bought the car the kid i bought it from said that he had hard wired the fan(so he cood turn it on himself). i want to change it back to stock so it comes on by itself. orginnaly he told me he hardwired it becuase the relay had blown- but now i am startin to belive that isnt the problem. is it normal for a 1991 camaro 305 tbi with ac to have only 1 fan? so far i have replaced the thermostat and the cooling fan switch. i also have the relay but i do not no where it goes. if anybody has pictures of a stock f an setup from a 91 305 i wood greatly appreciate it. the kid cut all the connectors off so i have no idea where all the wires go! thanx

never mind i firguerd it out. i think the problem was the fan switch.

F.Y.I. if you want the fans to turn on on a tbi 305 just turn ac to max... the fans will come on automatically. you can even diconnect the wiring on the a.c. near the firewall too. There is no reason to chop up wires for this mod.

I actually need to know the location of the same relay. My fan (92 tbi with same cooling setup) wont turn off and causes poor performance as it wont allow the engine to warm up. Also whats the part number for the temp sensor (the fan sensor in the radiator)? There are too many temp sensors...

Thanks,
Bryan

the relay i am unsure about. the sensor is the one one passenger side head (right guys?) Someone here knows what he's looking for...
