I'm a big fan of the "fix-it-yourself" movement that's springing up lately. We've gotten used to buying new stuff instead of repairing it because it's usually cheaper to replace than fix something!
There are even "fix-it-youself" shops opening with workbenches and tools to fix things like cars, bikes and electronics, with experts there to advise you while you do the work.
The display on my car stereo/climate control stopped working. The radio and AC still worked, but you couldn't see anything on the screen! Turns out this was a common problem with my car, and the dealer would replace the entire unit for about $700.00. (My car is an '04, and long past any warranty!) Well, no way I'm spending that kind of money!
So, my son and I found a U-Tube video with a guy showing us how to fix the problem, a tiny little fuse on a circuit-board in the radio that had gone out. We spent exactly $9.99 plus tax on a tool to pry the radio out of the dashboard. We took the unit out of the car, set it on the dining room table and took it apart. Dinner that night was at the kitchen counter!
We found the little fuse, and simply bridged the contacts with a soldering iron and a little wire. I know, I know, we could have put a new fuse in there, but what the heck, it's a 10 year old car! Doesn't have to be perfect.
Anyway, we put the radio back together, stuffed it back into place in the dashboard, turned the radio on an BINGO, there's the display lit up like Christmas!
Problem solved, $690.00 saved, and a nice afternoon and evening with my son!
