I have a 2005 Ford Five Hundred. In July, when the temps outside were around 102 degrees, I drove the car 150 miles back to my home, stopping about 45 minutes into the trip and shutting off the car and then stopping again about an hour later and tanking up with gas. At the last stop just a few blocks from home, I got out, shut off the car, went inside, came back out and nothing. No click, no noise. I thought it was the alternator or the starter or the battery. Took it to our mechanic and he said we blew a fuse. So, he replaced the fuse and also the starter relay. I asked him if it would have blown due to the heat, and he said “maybe”. He also said that if it happens again, he’ll mark the fuse so we can replace it and to let him know. Well, today the temp outside was 98 degrees and… it did it again. Fortunately in front of the house. I had driven it around town after work and made a few stops which perhaps put stress on the car. So we’re putting in a new fuse and see if that works.
The question…can high temps and humidity blow a fuse? The same fuse in a one month period?
