Question about 2007 Chevrolet Impala LS Sedan New Cars

1 Answer

I just bought a 2007 Chevrolet impala, 55k miles on it. No damage to it. The computer says, Engine Hot, A/C Off. Remote start doesnt work anymore. Check engine light is on, and the temperature gauge doesnt move from cold. There is also a foul smell coming from the vent that comes and goes every so often, smells like rotten eggs. I have replaced the battery, and the Engine Coolant Temperature Sensor, Nothing has changed. It went away when i replaced the battery, but it came back on the next day. What could be wrong..

You need a new gauge panel. Very common problem with these cars. There are people that can repair them like new.

SOURCE: temperature gauge not working 2005 chevrolet impala

There is a temperature sensor likely to be on your radiator. Make sure the connection is plugged in. Sometimes un-plugging and plugging it back will correct the issue. If not, you'll have to have some check if the sensor is faultly or if the electric wire is fault. You can check your fuse box. I don't think it's a fuse because other things on your instrument cluster would also not work.

Your catalytic converter is plugged up,  If you check the exhaust output at the tailpipe you will find it restricted.
Let me know if I  can assist further.

Ac is not blowing out cold air. You have to put gages on the system and it shows its has freon.Checked all fuses and relays. The two fans in engingine compartment do not come on when the ac is turned on but does when the engine gets hot. The compressor engages when turned on also.
If the magnetic clutch engages the compressor and still no cold air could be still low in freon or the HVAC unit.

Blower motor not working all the time...if I bang the dash near the glove box, it comes on then works great. Is this the switch assembly, the resistor problem, or should I be replacing the blower motor?

Low power message; engine nearly stalled. 2007 impala with 30,000 miles only

Oh, if the engine is getting an error code, scan the computer for the code.
However, I solved a problem for something like this on a 2008 Chevrolet Impala, which is similar to the 2007.

It may very wel be the TPS (Throttle Position Sensor) or the APS (Accelerator Position Sensor) which is faulty causing a code relating to the TPS not correlating with the transmission module.

So, if you are getting such a code, I would first try to replace the TPS, then if it isn't solved, try the APS.

If changing both doesn't solve the problem, maybe a wiring harness problem from these two sensors that input to the Transmission and Engine is faulty.

Good luck on this repair.

2007 chevy impala, automatic start stopped working and now the engine light in my dash is on?

this is normal operation for gm factory remote start if the ck engine light is on the remote start will be disabled. Because with the ck engine light means that there is something not operating properly and gm has put this in there system so you will not damage the engine by remote starting the vech with low coolant and let it run for 10 min and over heat the engine and cause engine damage.

When parked the heater does not work. Works fine if car is moving

Yes, Low coolant.
Leaking water pump or leaking rear head gasket very common on this engine.
Would be under the 5 years / 100k miles factory warranty.

If this car is remote start GM has a service bulletin out to do a computer flash to correct this problem, it will probably blow hot air in the summer if it remote started if you don't have the computer flash done. Hope this helps
