I need a radio manual so I can program my 94 satturn sl model car. I bought it used and no way to program the radio, no instructions.

No idea to totally truthful in my time the ultimate in advancement of technology was a radio cassete from the old valve car radios .Suggest you go to the dealer and ask if a instruction manual is available

you need radio pin code to type in using chanel buttons 1-4. You would have to get the code from dealer if it is factory radio.

Buy yourself a service manual from a auto parts store.They have torque specs and step by step instructions.

Do you happen to have the radio code? Sometimes people will put this with their owners manual. If not maybe you can track down the previous owner and see if they have it or would be willing to get it for you if they are the original owners.

Whenever you disconnect a car battery, the radio needs to have the Security code installed. It is for theft protection. It is the code you programed into it when you bought the car. If you bought the car new, the code is usually a series of zero's, usually 3 or 4. If you bought the car used, you may have to contact the previous owner, & ask what they used as a radio code, or if they recoded it. If that is not possible, you'll have to take it to a dealer, to have the radio reprogrammed. If you have an owners manual, it will be described in there also, on how to do it all.

Fuse box! Start there and check that the fuse is good.

it means low antifreeze in the overflow tank

Here are the wire colors and what they do in the system. Please rate my help.
