I own a 2003 Cadillac CTS. The engine light is on, I have no heat on the driver's side and the car is vibrating. I had it looked at by three different mechanics, all of which have not helped. I had the thermostat changed to a new one and the heat is still not working on the driver's side.
I was told the engine is heating up 50%, from what they said it is suppose to heat up at 95-100%
I had a diagnostic test and these were the codes: diagnosis because of engine trouble indicator light / diagnosis heating (left is not hot) test computer: Error Code P0128 Coolant Temp. Low/P0856 TCC torque req. Failed/C1277 signal/C1244 engine drag torque control controllscript Malfunction.
I was told the heating Valve has to be replaced in order to fix the heat in the drivers side and that may also stop the car from vibrating. They said to replace the valve it will take 8-10 hours of labor. Is this true?
They also told me the gasket cover is cracked, so now they have to replace all six sparkplugs, gasket and gasket cover. Is this accurate?
Please provide me with any opinions/advice you may have regarding my car.
Thanks in advance,
have the same problem?
