How to add freon to
You need to use a pressure manifold gauge:
http://www.amazon.com/Pit-Bull-CHIMG777-Conditioning-Manifold-Gauge/dp/B000VAQQ3Y/ref=sr_1_3?ie=UTF8&qid=1374522452&sr=8-3&keywords=r22+pressure+gaugeConnect the red hose to the high pressure side located in front of the radiator, connect the blue hose to the low pressure side located in front of the fuse box, there is a thick metallic tube that has a tire-style cap, unscrew that and attach it, purhcase R-12 refrigerant can of at least 1kg, then attach an adapter to the can and connect the yellow hose to this part, open up the flow valve and turn the can upside down while your car is running and the A/C is on. Check for pressure, the high side should have a high pressure and low side should be as low as possible while the compressor clicks on. Google for the exact pressure numbers as I don't remember. Just make sure that the AC compressor located at the bottom of the belts is engaged, this is engaged by the correct pressure setting automatically

Lost electrical power to fuel pump
There are many reasons why fuel pumps have no power, most (in tank) fuel pumps fail due to low fuel inside of tank.These fuel pumps turn at an alarming rate which in turn causes an alarming amount of heat. This heat is then dissipated by the fuel inside of the tank itself.If the driver/operator allows to run the fuel very low and continue to do so, this will over time allow for the fuel pump to overheat due to the ONLY source used to cool the fuel pump is the fuel inside of the fuel tank itself. Electrically, view the operator's manual or similar source to locate fuel pump fuse and/or relay of which will open the electrical path when the fuel pump overheats.This should be a pretty good starting point to locate/isolate electrical issue you may be experiencing.Good Hunting to you & hope this gets you back on the road soon!FASTESTNASCAR

Slow to start then stumbles
Slow to start, stumbling, stall completely,dies while driving.This all possibilities indicates towards problem with low fuel pressure.The flow of fuel is little bit low then actually required.If the fuel will not reach on time to the engine, then engine will stumble, stall and at last die.--------- So first thing to be checked in your case is fuel pressure.Get the fuel pressure checked, if its checked low, then problem is fuel pump and clogged fuel filter.---------
Other possibility can be problem with crank position sensor failure. It could be the magnet on the flywheel is the problem and not the Hall-effect sensor itself.Both the cam shaft and crank shaft sensor needs to be tested.The camshaft position sensor usually results in some sort of error codes such as misfires, while the crank position sensor does not. The crank sensor basically just tells the ECM that the engine is still running while the cam sensor deals with timing.----------
But most probably, this problem is related to problem with fuel pump and clogged fuel filter.If fuel pump pressure is checked ok and fuel pump anfd filter tested ok, then only check the other possible parts like, crank sensor, cam sensor, MAF filter, throttle body.------ The MAF( mass air flow) sensor and throttle body needs proper cleaning, sometimes.If the throttle body and MAF gets dirty with oil getting clogged there and dirt getting build up there, then this also causes the problem with fuel / air mixture. Getting this possibilities checked will help.Thanks.Helpmech.

Heat or air is not working, no air is coming out
Check for a strip fuse on the driver side strut mount, it will be in a tootsie roll sized case. If you dont have that fuse and have rotated all your fuses due to corrosion then blower motor may have gone out or regulator.

My 190e will only go
Something is wrong with the gearbox linkages or the valves. You need to take it out of the car to have a look at them - and at the valve body it commands.
Definitely a job for a shop, and it will be expensive.

I have a 230E Mercedes benz 1987 with an engine
The heavy vibration during braking sounds like it is warped disc rotors. This car has disc brakes on all wheels, so it could be one or all of them causing the problem. One way to identify whether it is the front or the rear is to observe the steering wheel while braking and feeling the vibrations. If the steering wheel is shimmying at the same frequency as the vibration, it is almost certain that it is the front. If not it is the rear. Do a visual inspection of your pads and rotors. You will probably see scoring in the rotors. It is a fairly easy do-it-yourself job with improved braking and that smooth Mercedes ride we all love.

Hi ,I have a 190e 2.6 my problem is she dies when
Not sure about this specific car... but most have an idle solenoid, a small elecrtric motor that has a rod that slides in and out pushing against the throttle, the mechanism that controls engine speed. When you gas pedal is pushed you can see the throttle moving in the engine compartment. Sometimes the problem is the solenoid itself, or sensors that feed the computer faulty info about how to maintain the idle. D you have a check engine light on? If so, some auto stores can determine what the problem is by using a device that asks the car computer what part triggered the check engine light. Please rate answer.

Mercedes 1987 190 D Turbo
The K relay or headlight relay goes bad in these and control all the lights and the bulb out indicator. It should be in the fuse box or under the screwed down cover connected to the fuse box.
The starter not working is the neutral safety switch on the transmission, when it goes bad cannot be started. It is a sefty feature to allow car not to be started in anything but park or neutral.
The electric windows maybe old dirty switches, remove the center console wood and move the good switch around and see if they work.

Car jerks with loud knock when shifting from park to drive
Ok the knock is your flex discs on the drive shaft are bad along with the carrier bearing. Replace before you get stranded or it comes loose.
Fuel distributor may need work if it is hard to start when warm, Replace OVP relay by battery also, its always an issue.
