2000 Chevrolet Impala blower motor work from 1-4 but not on 5th speed why?
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.

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.

2005 chevy impala holding high idle
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 .
