My blower for my heat in my car will not shut off. dropped off my car to the used dealer I bought it from, went to go pick it up last week Friday 4/12/13 because they said they fixed it. Put in new motor and sensor, turned on the car drove off the blower did not come on right away. Drove a little more than it came on full blast and tried to lower it and it would not turn off. Turned the car around went back to the dealer shut the car off took the key out the blower stayed on. The dealer couldn't understand why it happened because they put new parts in. So they still have my car, has anyone come up with a solution to this problem.

I am slightly disgusted that this problem has been reported by other people and yet nothing is being done about it. I think this is obviously a manufacter defect, and it should be recalled. I should not have to pay for this.

My heater blower was staying on even after the car was shut off and keys removed from the ignition. I had to disconnect the blower under the glove box. When I plugged it back in, to clear my windows, the wiring began smoking.(Tell me now MR. dealership that there is no danger.) My car filled with toxic fumes. NO HEALTH RISK THERE (I WAS DRIVING WHEN THE WIRING BEGAN TO SMOKE. ) There is no doubt that if someone else had been driving it would have ended in an accident or worse. I think it is ridiculous and insulting to be told that what is obviously a manufacturers and/or Design flaw has to be corrected at the customer's expense.I guess the cost of a new module (50 - 60 dollars) is worth more than a human life.I have driven GM cars almost exclusively my whole life.Now I will probably be looking elsewhere for someone who will back their product and shows a little care and concern for the health and safety of their customers.No wonder that European and Asian manufacturers are taking over our market. BE LOYAL TO YOUR CUSTOMERS AND THEY WILL BE LOYAL TO YOU.

I have the same issue as Stephen H. I am hoping his fix will cover my beef. It is kind of embarrassing having to connect and disconnect the battery everytime you need to drive; especially when you are driving a fairly classy car that isn't even paid off!

Found the problem !!!!!!!!! There is a module underneath the glove compartment, it is also connected to your windshield wipers. When you use your wipers, an intermittent charge fries your module and creates a cross wire directly to your battery. You need to replace the module and install a TCP hard wire in front of the module to absorb the power charge and prevent it from getting fried again. Hope this helps. Cost me $230.00 45 min labor. It's all good :-) Screw G.M.................

I just walked away from a bankruptcy, get my life together. I pay 19.5% interest to get this sweet looking ride. 3 months later the piece off crap blower motor won't shut off. Even after I take my key out.

The only way I can get it to stop is by unplugging the fuse under the hood. (30 amp) Why in the world do they have a fuse box under the hood exposed to all the elements ? I guess I should have brought a technician with me when I picked this junk.

The rest of the car still functions, I just freeze my ass off. Fortunately my company pays for my car allowance, so the 19.5% doesn't bother me. Next year I intend on trading it in as I am re-establishing my credit at the same time I'll get lower financing.

Guess what ? Next year G.M can kiss my ass, As a matter of fact they can kiss my ass this year, cause this year it's freezing. I only had the damn thing for 3 months and the Barrie ford dealership says there's only 30 days on my warranty. G.M wants $105 hour to find the problem.

That's like going to McDonalds buying a cheese burger and getting charged to find out why my pickle is rotten. Are you kidding me ?

It's one thing to have a malfunction and another to be told, It's your problem. I only have 76,000km. Why should I pay for their shoddy workmanship. To bad Walmart doesn't manufacture vehicles, they have a great return policy.

Dealership says, If it doesn't have any life threatening issues, no recall. G.M has outsmarted themselves. They've suckered so many people into paying for their rotten pickles that now everyone is starting to consider foreign.

Imagine ordering a quarter chicken dinner at Swiss chalet, and you find a hair in your food and the waitress tells you you have to pay to find out whose hair it is ?

Not life threatening ? If I didn't notice the blower was still running, I would have come back with a dead battery. That makes me stranded in the freezing cold. A light bulb I understand. But a vehicle that keeps running, preventing you from shutting it down, could be potentially be life threatening. What if it overheats, kills your battery or arcs into something else in the engine.

I'm sorry, but I was always under the impression that when you have a vehicle the basic policy is to have all functions turn off. Recall, Recall, Recall.

It appears that the customer is always wrong. With service like this, I look forward to G.M's demise. Imagine Rick Wagoner of GM finds out he has a faulty switch in his private jet ? Good luck Rick, We're all down here routing for you...............
