1994 sentra the relay above the junction box behind the fuse block is clicking rapidly and the battery and brake
lights on the dash flash accordingly
JA: Many things can cause a car to make those weird sounds. Some simple, some complicated. Fortunately, the mechanic I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so he can help you best.
Customer: The clicking/flashing speeds up as I slow the engine or lessen the electrical load
JA: Are you hoping to fix this yourself?
JA: Great! What have you tried so far?
Customer: All I have done is identify the relay making the noise but don't know what it is for
JA: Is there anything else the Nissan Mechanic should be aware of about your Nissan?
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Nissan Mechanic about your situation and then connect you two.
