Rear-Defrost Relay Does anyone know of a replacement p/n for the rear-defrost relay? I can only find used ones on Ebay and I don't trust 30 year old relays..lol The relay under the passenger dash, not the on/off button. My issues is my rear-defrost doesn't stay on more than 2 min at a time. Doing research here on the boards I've come to the conclusion that my issue is the relay. It still "clicks" when I turn it on and off, but it should stay on for much longer than 2 min at a time. |
Re: Rear-Defrost Relay No one knows of a good replacement relay for the rear defrost? |
Time Out You won’t find one unless it’s dealer NOS. If the 2 minutes is repeatable it’s not the fault of the relay, it’s the timer. The following circuit can replace your defective timer: http://s6.postimg.org/z7xk0vi4h/TIMER_NON_NASCAR.png C1 and R1 control the amount of time. Start with 270μf* for C1, and 8.2K* for R1. I estimate 5 minutes for the aforementioned. If more time is desired increase C1 and or R1. To make it easy you can use a potentiometer for R1 so you can dial in the time wanted. ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ *Or the closest you can get. ◙◙◙◙◙◙◙◙◙◙◙◙◙◙◙ Happy Racing! ◙◙◙◙◙◙◙◙◙◙◙◙◙◙◙ Even Tho I Might Destroy The Car During The Race, At Least It Looks Gorgeous At The Start |

Time Out Yes so it might be easier to replace the relay and timer. Nomenclature evolves and people refer to the entire assembly as a ‘relay’. ◙◙◙◙◙◙◙◙◙◙◙◙◙◙◙ Happy Racing! ◙◙◙◙◙◙◙◙◙◙◙◙◙◙◙ Even Tho I Might Destroy The Car During The Race, At Least It Looks Gorgeous At The Start |
Re: Rear-Defrost Relay I’m also looking for a timer, or at least I was. It rained today so I thought I would give it another try. The darn thing worked. The light was on at least 5 min. and I could slowly start to see through the window. How long it will last is another story. |
