The blower motor relay is energized when the Blower Motor Control is set to the High position. This removes the blower motor resistors from the circuit and battery voltage is then applied directly from the HVAC BLO fuse (RH IP Accessory Wiring Junction Block) to the blower motor though the relay switch contacts. The blower motor then runs at high speed.
HVAC Blower Controls Circuit Description
The blower motor is a variable speed motor. The motor operates at a higher rate when voltage is increased to the maximum level.
The blower motor resistors reduce the voltage supplied from the A/C FAN fuse (LH IP Accessory Wiring Junction Block) when the blower control is set at low and medium speeds (speeds 1-4). The blower motor relay is energized when the Blower Motor Control is set to the High position. This removes the blower motor resistors from the circuit and battery voltage is then applied directly from the HVAC BLO fuse (RH IP Accessory Wiring Junction Block) to the blower motor though the relay switch contacts. The blower motor then runs at high speed.
You can't use High Beams as dipped, the spread is different. Just go to another garage, it can only be the bulbs, the connection, the fuses or the relay. In fact you can check all those yourself! It appears to be a known issue on the Impala. Look at the videos

if no signs of leak around motor or floor then internal leak and burning it off --buy or borrow [auto parts stores ] a coolant pressure tester ---also pull and read plugs
yes if u buy ignition switch from the junk yard make sure they have it plug or u need to use the right key from the right ignition.. u cant use your own key sir u need the original key of the ignition switch where u took the parts.god bless
I take help from online websites that have this service like helping in repair some like reliable-store have instant help.. others are a bit slow which I don't prefer... rest is up to u.. U can also get free manuals
If you're finding it difficult to service/repair your
car
I know a website that has every info on all vehicles and vehicle problems, with their solution In detail.. it's www.reliable-store.com
What engine does it have ? 3.4 or 3.8 L
Turns over but wont catch ??? turns over but won't start an run !!!!!! What wire did you check for Ground ? Looking at a wiring diagram so you know which wire is what . Black/ white wire , pin K at the ICM - ignition control module . This is ground for ICM - ground point G-111 . Looking at service repair manual would tell you where this ground is located . G111 (VIN K)
Top right of the engine, below the ignition control module.
Suggest you watch this training video
GM Bypass Ignition System Operation part 1
mode door in ducting either stuck or failed --try turning the selector to another setting like floor /dash then another to see if it changes if no change actuator may have failed
A temp sensor out of range giving a false cold reading can cause high idle . A MAP sensor can also cause high idle by advancing the timing resulting in higher idle .
