What condition are the cables on the car in? They can develope corrosion and become fractured or broken. Check both the positive and negative cables from the battery all the way to the other end where they connect to the motor and block
Depends on which entertainment option you have. If it has the Bose option, the amp is behind the back seat, and the sub woofer is a the center of the rear shelf panel.
for heavy machinery cars etc. luckily there are many websites
that can help you repair
for eg site like reliable-store is very active in this.. instant help, emails and all that's fantastic
No the torque converter clutch solenoid won't have anything to do with it . More then likely it's the internal mode switch . This tell's the computer which gear is selected , then the PCM energizes the correct shift solenoid . The PCM will send this info to the instrument cluster over the class 2 serial data network . The instrument cluster has a microprocessor with logic programmed into it. More then likely has DTC'S - diagnostic trouble codes stored in one of the computers on the vehicle . Your best bet , take it to a qualified repair shop .
The internal mode switch (IMS) is a sliding contact electrical switch assembly that corresponds to the PRNDL position selected. Each of the PRNDL positions has a unique ground pattern on the four wires from the PCM. The IMS consists of two major components: The housing, which houses the tracks and makes up the stationary contacts. The insulator assembly makes up the moving contacts and is linked to the detent lever. The range detection is accomplished by securing the moving contacts of the IMS to the detent lever. When the driver selects a PRNDL position, the detent lever inside the transaxle rotates. This slides the IMS moving contacts which in return grounds the four wires in a unique pattern for each gear selection corresponding to the PRNDL position selected. The IMS is electrically connected by five wires (four of which the PCM supplies voltage to and one wire that is a common ground) to the transaxle pass through connector.
PRNDL Display
The IPC is equipped with a vacuum fluorescent (VF) PRNDL display. The IPC PRNDL information is received from PCM via class 2 serial data message.
Turn OFF the ignition.
Install a scan tool.
Start the engine.
Place the gear shifter in the following gears:
• PARK
• REVERSE
• NEUTRAL
• DRIVE
Observe the IMS parameter in the powertrain control module (PCM) data display.
Does the scan tool indicate that the IMS parameter is the same as the PRNDL display for all gears?
If you disconnect the battery, in most cars this will reset all systems. However from your description I would expect that the problem is a faulty actuator
Best bet ,have it diagnosed at a qualified repair shop . Has a couple of electronic modules involved . Driver door module , heated seat module . But before you criticizes have a look at the wiring diagram an tell me you understand what's happening .Free wiring diagrams here http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model and engine size . Under system click on interior & driver amenity , then under subsystem click heated seats . Click the search button then the blue link . Hooking up a scan tool that can communicate with driver door module for the purpose of checking for DTC'S diagnostic trouble code's .
Sounds like a failing pump in the transmission or a torque converter problem. Check for any error codes (DTCs) using a code checker to see what is setting the warning. Next stop is probably a transmission shop.
Check the actuator motor on the heater box inside down by the floor in the center of the car. The motor moves the paddles inside the heater to direct the heat and the ac. It is a small motor and on your car with climate control there is probably two of the motors. One for the passenger side and one for the driver side.
If the warmed up temperature is OK, probably not an airlock in the system. As for "check cooling level", this is shown when the integral level sensor in the reservoir tank is either not functioning or you have a bad electrical collection. This integral level sensor is not replaceable - you will need to replace the tank.
Two cooling fans controlled by three relay's . If only one fan is working ,that could be a problem .
Coolant Level Sensor Description
The coolant level sensor monitors the coolant level in the cooling system and indicates if the coolant is low. This sensor is located at the base of the radiator surge tank and is not serviceable.
CHECK COOLANT LEVEL (2)
The IPC receives a discrete input from the engine coolant level switch. The engine coolant level switch is normally closed. When the engine coolant is low, the engine coolant level switch opens. When the IPC receives an open signal from the engine coolant level switch, the IPC displays the message on the DIC.
Relay Driven Dual Cooling Fan Diagnostics There are using a pontiac , by your cadillac is the same .
Could be the serpentine belt rubbing on something, but is probably a bearing problem in the belt idler pulley. However, it could be the power steering pump, AC compressor clutch or generator. As the water pump is at the opposite end of the engine, it's probably not that.
This problem is out side the gas tank , has nothing to do with the fuel pump or fuel level sending unit inside the gas tank .DTC P0446 EVAP Vent Solenoid Valve Control System . Do you know anything about automotive evaporative emission system ?
Wells EVAP Training with Sgt Tech P0440 P0441 P0442 etc
This DTC tests the evaporative emission (EVAP) system for a restricted or blocked EVAP vent path. The control module commands the EVAP canister purge solenoid Open and the EVAP canister vent solenoid Closed. This allows vacuum to be applied to the EVAP system. Once a calibrated vacuum level has been reached, the control module commands the EVAP canister purge solenoid Closed and the EVAP canister vent solenoid Open. The control module monitors the fuel tank pressure (FTP) sensor for a decrease in vacuum. If the vacuum does not decrease to near 0 inches H2O in a calibrated time, this DTC sets.
