The remote door opener don't work even with new battery installed. However it works (sometimes) when you turn on the inition switch and imediately afterward it works. What can cause this kind of problem? The Dealership think its my remote door openers and I can't see both of them going bad at the same time....
I have a 2003 cadillac cts and i have begin to hear a roaring
noise that sounds like it is coming from the rear end. Took it
to the dealership and they said it was my tires. Bought new tires
and it is still doing the same thing.
I bought my 2003 Cadillac CTS on July 28, 2002. This car really takes off. I have to reign it in, just a couple of speeding tickets. It has about 150,000 miles, no oil burning. On a long trip I get around 28 mpg,good for the 3.2 V6. My problems are, the third brake light is made with neon type light bulbs. It died out last year, I put in a temporary inside the window cheap stop third light, it is still there. The third light is over $250. This is a common problem with water leaking into the light, and burning it out. Another problem is the plastic frame on the back of the backup lights came off and broke. The dealer wants only $600 for its replacement. I glued it back on, but it is still broken. Why did it fall off; because you need to take it off to replace the backup light bulbs, so no glue...otherwise the car is great and still looks great (garaged). Adolph41
Brought this car new in 2003. Last week the windshield wipers would not turn off. Now it is in the shop and the part cost $230.00 and the labor is about $150.00.
