Other than the country where the relay is made
Could there be another reason why two AC relays have failed on my car in 5 years? Same scenario both times. Turn on AC, compressor doesn't engage. hit a few bumps in the road and CLICK, it's on. Last time it happened, I replaced both the AC and fuel pump relays thinking that since they were both orig., I wanted to prevent a potential no-start. But here I am again. Turn on AC and occasionally have to tap the relay.
