Hello, I hope this is the right place to post this.
I have a 2005 Mazda 3 that has a problem with the windshield wipers.

We let the car sit for about 6 months and had to change the battery, after that everything was fine except the front windshield wipers would work intermittently. Eventually, they didn’t work at all.
The rear wipers are fine and the wiper fluid works fine.
My garage said I needed to contact the dealership to fix the problem,
something to do with the wiper relay junction box.

Anyway, I took it to the Mazda dealership in my area and the wipers are back to intermittent.
I have not contacted the dealership about this yet because of funds and I live in rainy climate and the dealership is an hour drive from my town.
Feeling at my wits end, I’m wondering if I should sell the vehicle. I’ve put a few grand into it including new tires, but I don’t think anyone would want to buy a vehicle that has faulty wipers. Is it even worth anything at this point?

Any advice is very much appriciated!
