Well, here is the extent of my deal. I got last month a Chevrolet Malibu 2002. I noticed that , progresivelly more and more the turn signals on it were not functioning for some ammount of time. They would stop working when on the road for some time and then turn themselves on again either later down the road or after I stopped and parked. I am talking about both the lt;- -gt; and the lights themselves on both sides.I took it into an auto shop last week, they charged me a $135 for an extensive diagnostic. They checked wires, fuses, bulbs and took apart the steering column. Once in the steering column they said the multifunction switch was bad and it needs to be replaced to fix the problem. I happily did so especially since they have a 12 month 12,000 mile warranty on repair. Ended up being charged for part, labor and so on over $450.After I got out of the shop I noticed that the switch when pressing down and up on it felt incredibly tight wheares it was loose before.
Since the switch felt tight and operated OK for a period and then went loose again and started acting up at the same time, it does appear that the cause is the same as the first go around. Return to the shop and ask them to repair it under warranty. My guess is that either it (the new switch) was not installed correctly or they actually repaired the old one and the repair did not hold (constitutes fraud as you paid for a new one). Be polite, but be on your toes. There should be no charge this time around. If they try to stick you for more money, firm up on them (say no) and talk to your DA, and find an honest mechanic.
bring it back to the shop and let them fix it you should be under a warranty use the warranty that they gave you with the repairs if they don't make good in timely manner a small claims is in order make sure you document all comunication and save all paperwork you may be able to catch car rental if they keep it too long
You answered your own question when you said the shop has a 12 month, 12000 mile warranty on repairs.
