Loose impeller causing Aveo overheat issue
Problem: The vehicle was brought to the shop because it was overheating only on short trips around town. It was fine on the freeway. The shop replaced the thermostat, radiator and coolant. The cooling fans were operating correctly. After all the repairs, the engine was still overheating.
Problem: The customer complained of intermittent problems with the head lamps going off and on by themselves and fuel pump staying on, even with the key off. There were other random, intermittent electrical problems too. The malfunction indicator lamp (MIL) was on.
Problem: During the test drive after the automatic transmission was rebuilt and reinstalled in the truck, the engine would stall on deceleration or anytime the gas pedal was released. The technician connected a scan tool and found no diagnostic trouble codes and all the scan tool data appeared to be correct.
Tail Light Condensation Causes Driver’s Window to Roll Down
Problem: The vehicle was brought to the shop because the driver’s door window started going down intermittently when the ignition key was turned to the on position. Once down, it could be closed and would stay closed until the key was turned off then back on again. The technician noticed there was condensation in the left tail lamp.
