Low coolant level in engine will result in no coolant reaching interior heat exchanger. Otherwise, check environmental controls. Feel heater hoses under hood to see if they get warm when engine is warm. Could be control valve is not being opened to allow hot coolant into interior heat exchanger.

Manifoild air leak causing engine to idle too fast. Check for air hose leaks. Some are palstic mated with rubber hose sections. Both can crack and leak. If engine stalls when stopped at light, torque converter may not be unlocking.

No. It is connected directly to a temp sensor in the cooling system. A second temp sensor is dedicated to the computer. If coolant is too low, steam in the upper part of the engine can cause temperautre misreads. Check coolant level. If o.k., replace guage temp sensor.

sounds like the starter is failing

try looking at coil packs or possibly if the car has one alarm system in case immobiliser has gone

check your ignition system. A good quality HEI tester is quite inexpensive

Can not guess for you Always need the car to check out Have you even looked yourself ? Could be the fuel line coming to the motor, rusted away Better not use it or start it,until you fix the issue

you can take the strut cartridge from the top,without disassembling spring and knuckle,there are there are 3 15 mm bolt on strut 9need to be torqued to 24 LB FEET) then you need special tool to take the strut mount and cover out ,(it is 24 mm bolt that you have to put #50 torx bit in the center to keep strut rod from tuning NEED 59 LB FEET of torque) ,then you take the bumper,mount and the boot out to put the special tool to keep the strut cartridge in place or it will shift side way ,and you have to tow the car to shop to get it done!!!,after that you use special tool to loosen the cartridge cover (NEED 82 LB FEET WHEN PUT BACK)take the strut out,suck the oil with the hand pump out,and put 50CC back,as it needed to help cool down the strut,( when you put new strut in the oil level should cover half of the strut no more) ,and reverse the process after that, this is the tool you need, Alltrade 648609 Kit 19 General Motors Body Strut Remover Tool Set

Check the blend door.

sounds like you might have a air lock in the cooling system I would have to know what engine is in it

water pump, air lock , blocked heater matrix , three to get you started does the engine over heat, if not then not likely to be the water pump, has the coolant level dropped, if so top up and bleed and open and close temp control for heater at same time , need a helper , do this for ten minutes so the engine is at a good temp ,making sure coolant is topped up, if after all this still no heat i'd suggest having the heater matrix cleaned through or even replaced

you got it ,its vacuum controlled

Could be the central locking motor or linkage that need looking at. Can you hear the motor move in the driver door? If so the linkage is at fault, if not then it's the motor

the engine back fires

Alternator is going bad.

POSIBLE CAUSE O YOU NEED A NEW COIL PACK OR A IGNITION MODULE

bad module or bad coil

Unhook the window motor and see if the door lock will work ....if. Ot go to salvage head and pick up new switch

if there was no collision and the air bag light is on there is a code set in the module that needs to be pulled then checked out. with the light on you have no air bag operation. the module can only be reset if the problem is corrected and the use of a scan tool is used to reset module.

check all fuses and if that isn't it then tap into another power source of the same amperage rating
