Is this relay the same relay my 2004 Honda Civic LX uses that says 16z3a31a on it ?

I don't know about your particular car, but despite Amazon's recommendation that this part fits my car, it doesn't. And I am not the only one complaining that I purchased the wrong part for my vehicle, based on Amazon's assurance that is the right one. Hope this helps.

Will these actually fit a 2014 Nissan Titan Pro 4x? I have bought some that said they fit my truck but they do not.

Prob not bud I found the same issue and never received a refund but they stated they would fit I purchased them for a 2002 Durango slt and they did not so I will advise to check for yourself the pins and the voltage or amps and make sure they match regardless of what Amazon says . Because they don’t know anything and this continues to happen ….

Do these things last long? Or do they keep blowing and thats why they send 4 of them?

So far so good with mine. They live in the toolbox with the battery on the tongue of my trailer which sits outside.
