THis ain't no question....
why would you stop payment on a check anyway
Check your fuses in your fuse block you should have a fuse that says "gauges". If you fuses check good take it to a mechanic shop.
how to start a mechanic shop
You can look in the phonebook for a certified auto repair shop. Also you could check the internet for mechanic shops. Many auto places will refer you to a certain mechanic or shop.
Is the auto insurance provider required to make your repair claim check to the repair shop?
Most any mechanic shop would have one.

Most car payment calculators are accurate but you should always use your own calculator and check the math. My advice is always to shop around and research the quality of the payment calculator service.
It is true that if the mechanical shop is holding the car because of non-payment of the repair, they would need to have filed a mechanic's lien on the vehicle in order to legally detain it. However: If your complaint is that the car was not fixed properly you shuold have taken the mechanic to small claims court, rather than just not paid him.
Depends on the mechanic shop
You need a repair licence to open a repair shop. You don't need a licence to be a mechanic but, it would be to your benefit to be a certified mechanic.
Depends. If the cash payment is the payment of debt, then the payment cannot be refused, as long as the money is still legal tender. Cents stop being legal tender after a certain amount, which is why you cannot try to pay a debt using 10,000 cents for example, this can be legally refused. If it's payment in a shop, a shop has the right to refuse service to anyone as long as it is not for a racial, age, gender related reason. They do not 'have' to accept any offer of payment, nor are they disallowed from accepting payment in other forms.
To find a good Mechanic or Shop call the B.A.R (Bureau Of Automotive Repair) and ask for information on the best shop in your area...
