Thanks.

Sounds like voltage regulator in the alternator, have auto-zone do a charging check, may need new alternator.

yes if it has power steering . look on the left front of the engine.....

Could be different problems. The blower uses a resistor to regulate fan speed, the resistor could be faulty.You would need to know if the radiator is full of coolant and if both heater hoses are getting hot. There may be a temp control valve in one heater hose that is not opening up to allow flow thru the heater core.

fill it with fluid and look for the leak the system is under the most pressure when the front wheels are all the way to one side or the other..(all the way left or all the way right) if a helper can turn the wheel, you can inspect for the leak to determine where its at..if a hose is craked open, you can cut it and install a ferrule and clamps on it,,if its the pump, it needs replaced..and if the pump growls already due to low fluids it will need replaced very soon anyway..good luck it can be driven carefully but I dont sugest it..

I honestly had the same problem, and it was oil related. how does the oil gauge react when you are turning corners?

What is the fault code nunmber.

It could be a bad thermostat or a water pump that is not pumping coolant. Even a miss routed serpentine belt causing the etc--------------------------------------------------------------PSA BSI tool for Peugeot and Citroen Odometer v1.2

be checking the vacuum controls that operate the baffle doors in the ductwork.. this should rectify the issue..

check your body grounds.

in the alternator

My first guess would be water or moisture in a wiring harness or wiring connector.

if the led is working and the remote does not work then it will need to be resyincronised which is easy using a t300 scanner all good auto electricians carry themi have all the wiring diagramsand fault diagnosis from the manufactures download from caralarmandradio.com

This can be caused by a few things. I have had this happen. First, check to make sure the starter bolts are tight. This is the most likely. Second, pull the starter and check to see if the gear is all there and everything is tight. Third, pull the inspection plat and check the fly wheel/flex plate has all its teeth. If everything seems ok, I would replace starter, the cheapest fix first and go from there.
