A new flasher control will not solve the problem because it's made for filament bulbs. Your LEDs draw much less current than the standard filament bulbs so the thermo-electric flasher doesn't heat up enough to flash slowly. The solution is explained very well at www.superbrightleds.com from which I recently received LED turn signals. The solution is to install a load resistor across one of the bulb sockets so the control unit will flash at its normal rate. I think this load resistor is 12 ohms, but go to their site to be sure. If you try to get a load resistor from Radio Shack, make sure it can handle the current. A 1 watt resistor will burn up. The safest is to order it from the above company. Some newer cars will flash "bulb out" when LEDs are installed and some disable the cruise control because they sense much less than standard load when LEDs are used. God bless America and Chevy Cobalts. I have a beautiful 2007 red coupe with red wheel covers and I get 38- 41 PMG highway consistently with the 2.2 liter engine and automatic. I attribute this high MPG to my carefully breaking it in for 1200 miles (instead of the standard 500) by varying the engine RPMs every mile or two. It's tedious, but if we treat a Cobalt well, it will treat us well in return.

#19 of 38 2007 cobalt fuel problem and hesitation
May 26, 2010 (5:26 am)
i have had my cobalt for 3 years now and since day one the fuel consumption has been horrible. I fill up alot i get 160 to 170 miles per tank which breaks down to 14 to 15 mpg. I have had it at the dealer so many times i just hate going anymore they have replaced fuel pump, fuel tank, evap lines, gas cap. I only have 35k on the car and at first they told me it was normal you get better down the line but still is real bad mpg i do hwy and city driving and i do feel a slight hesitation while sitting at red lights and a few times the car stalled. I bought 2 cobalts the same day and the other one got around 300 miles a tank with about 27 mpg and my brother beats his car. Is there any one else that has had this problem or no a real fix maybe im tired of putting $90+ a week in gas in my car.

Another possibility is that the computers in the car are messed up for some reason and your mixture is off. That's definitely what it may be. That can be a number of things, though, so idk. I would test injectors, replace plugs and wires, and ohm/volt the different connections to wiring harnesses.

#26 of 38 2007 Cobalt - Odd Issues [wiring?]
Jul 16, 2010 (11:53 am)
I have an intermittent issue with my Cobalt. It's become more permanent than intermittent recently. The turn signal used to click, like any car, when it is activated but that annoying click click click to let you know it's on does not happen anymore. The turn signals still function perfectly aside from this. After this had gone on for a few days off and on, I noticed that the speaker in my driver side door did not work. Now, I listen to music pretty loud so I thought I blew the speaker. After a couple days of trying to figure out why it was working sometimes and others not, I realized the speaker is dead at the same time the signal doesn't click. Also, when this is happening, the ding that lets you know your keys are in the ignition when you open the door does not ding. I think it may be wiring but I'm really not sure and really don't know where to start. It seems like if it were a fuse that it would just blow and none of it would work til I change it, instead of sometimes it does and sometimes it doesn't.
So, to summarize:
annoying turn signal click doesn't click
ding when the keys are in the ignition when the door opens doesn't ding
driver's door speaker does not work
this intermittent although it is becoming more permanent
Any help would be greatly appreciated! Thanks
