Fault code P1664 is the Electric Heater Open current and stored.It is a most common fault on these models. If you will try to find it is in the engine compartment by the engine block above the starter motor. As I remember are not repairable and you have to change it. I personally suggest ask a qualified technician to do the job for you.Ask and how much is the cost.

Hi K, Have you checked the thermostat? Also insect the cooling fan operation, and look for any leakage. Let me know how you get on and what you discover. Regards John

this means that it has detected a rich condition. You can get this with a dirty maf sensor suually caused by paper filters, a vacuum in a hose or connection or a fuel pressure problem. Dirty mafs are easily cleaned even at home with maf spray cleaner. As long as you are careful not to physically touch the actual'sensor you can't hurrt it if it is still good.

for the powerstearing check the oil and refull when nessesary,turn engine on turn 5 times hole the way left and 5 times hole the way right.check level oil again refull when needed.the white smoke on that spotyou say can leak from diesel.

The "crank" is located in the bottom end of the engine and normally the sensor is around there too.

HelloThe engine and transmission in this cars drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPEDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM

Are you check if have voltage regulator in good condicion (if apply).

I think you need to replace the wiper switch. Removing the switch can be a pain.. Firstly, you need to remove the trim around the steering column. Now this may be difficult as you may need to remove the steering wheel first. This is complicated by the fact that you have Airbag on the wheel that must be disarmed properly by a tech...Scared yet..? Don't be, ok if you can get the trims off, check and see if the switch is screwed into the column retainer. If you can see the screw heads by looking down the shaft of the switch, good, remove the screws and the switch should come out just enough for you to unlock the wiring, unlock the wiring taking note of which plugs go where and take the stalk out. If you cannot see any screws, then remove the steering wheel as it may all be one assembly. Once the wheel is off and the trims are off, there should be four screws holding the assembly onto the column. Once these are out and you have released the wiring, the switch assembly should come out. Next, look for the wires which go up inside the stalk itself and take note of where they connect. Now, on the end of the stalk, there should be a small cap which covers a clip which holds the switch onto the end of the stalk. Gently prise out the cap and the clip (dont lose either the cap or the clip) and draw the switch off the end of the stalk. If it is the type I am thinking of, the switch will come off and you can see the wiring into the switch. Now, gently give each wire a tug, that is, pull it back from the switch. If any of the wires seems to stretch, then replace that wire, crimp or solder a new length of wire to the switch and to the connection on the other end. If non of the wires stretch, pull them the other way, down to the main assembly and replace any that stretch.Then, reassemble the switch and stalk, replace the trims and refit the steering wheel.If you have an airbag in the steering wheel, you may need special screwdriver tips to remove the screws holding the steering wheel cover on, the nut holding the wheel on is under this cover. They usually use torx screws in here.The steering wheel is fitted to a tapered shaft so leave the nut on a couple of threads and by placing both feet on the fllor behind the pedals and pulling, you can usually get the wheel off otherwise you may have to use a wheel puller. NEVER use a hammer on this assembly EVER !!!!Once the airbag is off, dont turn the ignition on as this may set a fault code and cause the airbag lamp to come on disabling the airbag system. DONT probe any wires that have a yellow sheath or outer covering or yellow connectors on them. You really dont want an airbag going off anywhere near your head !!!Take your time and if you need too, draw little pictures of where things went to remind you when you reassemble things.Now, there is always the chance that you have a body control module, this means that when you operate a switch, all you are doing is sending a signal to a computer. This computer then operates the device. If this is the case then you need to check the switch ( yes I know this is a pain) but then you may need to check the control module as well. This may be better done by a professional.
