EGR COOLER LEAK, COST $2150 FOR THER PART.

A/C LIGHT ON, THE BLEND DOOR MOTOR NEED REPLACEMENT

MANY PEOPLE COMPLAINT THEIR A/C SYSTME IS NOT COLD ENOUGH, BUT IF YOU PUT HAND CLOSE TO THE VENT, YOU CAN STILL FEEL COOL. THE REASON IS THE CABIN AIR FILTER DIRTY, BLOCK THE COOL AIR FLOW. SIMPLY JUST DUMP IT OR REPLACE WILL DO THE JOB AND SAVE MONEY.

VEHICLE HAS NO POWER, CHECK WITH SCANNER, WITH TURBO WASTE GATE CLOSED, 3 PSI MAP INCREASE AT 3000RPM. REPLACE TURBO.

THE LOW AND HIGH SIDE OF THE A/C SYSTEM TOO HIGH, LOW SIDE IS OVER 100PSI, AND THE HIGH SIDE IS OVER 400PSI. THE REFRIGENT IS RIGHT AMOUNT, CHECK THE RADIATOR FAN. THE MAIN FAN IS DRIVEN BY A BELT, OK, BUT THE LOW RADIATOR FAN IS AN ELECTRIC FAN, NOT WORKING. IT WAS DISCONNECTED. RECONNECT, A/C PRESSURE GOES BACK TO NORMAL.A/C COLD AGAIN.

MAIN RELAY IS THE GLITCH.

THE GLASS KEEPS COMES OUT OF THE REGULATOR. AFTER REPLACING THE REGUALTOR, IT IS GOOD FOR COUPLE MONTHS, THEN BROKE AGAIN. REMOVE THE WINDOW RUN, EXPOSING THE TRUTH: THE LOWER TRACK HAD A TON GUE THAT JOINT THE UPPER TRACK BROKEN, IT CAN JIG OUT ANYTIME AND JAMB THE MOVEMENT OF THE GLASS. THAT WILL BREAK THE JOINT BETWEEN THE GLASS AND THE REGULATOR.

THE WASHER HEATING ELEMENT IS LEAKING. IT USED COOLANT TO HEAT UP WASHER FLUID. COMMON PROBLEM FOR MB.

THE EXPANSION VALVE IS FAULTY. THE COMPREESOR FAILURE CREATED LOTS OF METAL FILE. THEY DAMAGED THE VAVLE.

TO REPLACE IT, THE OUTSIDE A/C NEED TO REMOVE TO EXPOSE THE STUD ON THE VALVE. THE STUD NEED TO BE REMOVE SO THE COVER OF THE VALVE CAN BE REMOVED.

WELL, IT IS HARD TO FIND THE OPEN BUTTON FOR THE TOP OF THIS CAR. IT IS LOCATED IN A BOX ON THE CENTER CONSOLE. THE BOX LOOKS LIKE AN ARM REST FOR THE DRIVER, I THINK IT IS A STORAGE BOX AT THE FIRST SIGHT. LOL.

WHAT A STUPID DESIGN!
