Question about Mercedes-Benz 300-Class

1 Answer

Battery was disconnected before I got the 1991 300TE stationwagon. Everything worked beautifully except the radio and the fan/air-conditioning controls. I found the "code" number for the radio and now it works just fine. Any thoughts about re-instating the fan and a/c? Thank you very much. Colin Campbell

Hello! I can not see any reason the AC would quit working after a battery disconnect...Lets start by checking fuses: 7 (16A) and D (16A)...Also, The refrigerant high pressure switch (left front of engine compartment) may be open...Check the Brown/White wire in its plug for a ground when AC is on...

1995 nissan maxima alternator replacement


1995-98 Models
  1. Disconnect the negative battery terminal.
  2. Remove the splash guard on the right side of the vehicle.
  3. Loosen the alternator belt idler pulley.
  4. Slip the drive belt off the alternator pulley.
  5. Remove the four air conditioning compressor mounting bolts.
  6. Remove the radiator fan and fan shroud.
  7. Move the air conditioning compressor forward.
  8. Disconnect the alternator harness connector.
  9. Remove the alternator mounting bolts, and lower the alternator from the vehicle.
To install:
  1. Hold the alternator in place and install the mounting bolts.
  2. Plug in the alternator harness connector.
  3. Move the air conditioning compressor back into location.
  4. Install the radiator cooling fan and shroud.
  5. Install the air conditioning compressor mounting bolts.

Proper belt tension is important. A belt that is too tight may cause alternator bearing failure; one that is too loose will cause a gradual battery discharge and/or belt slippage, resulting in belt breakage from overheating.

Tip

Tips for operating Air conditioning system on Toyota Hilux and someother...


To cool off your Toyota after it has been parked in the hot sun, drive with the windows open for a few minutes. This vents the hot air, allowing the air conditioning to cool the interior more quickly.

Make sure the air intake grilles in front of the windshield are not blocked (by leaves or snow, for example).

On humid, do not blow cold air on the windshield. The windshield could fog up because of the difference in air temperature on the inside and outside of the windshield.

Keep the area under the front seats clear to allow air to circulate throughout the vehicle.

On cold days, set the fan speed to high for a minute to help clear the intake ducts of snow or moisture. This can reduce the amount of fogging on the windows.

When driving on dusty roads, close all windows. If dust thrown up b the vehicle is still drawn into the vehicle after closing the windows, it is recommended that the in intake be set to FRESH and the fan speed to any setting except "OFF".

If following another vehicle on a dusty road, or driving in windy and dusty conditions, it is recommended that the air intake be temporarily set to RECIRCULATE, which will close off the outside passage and prevent outside air and dust from entering the vehicle interior.

HEATING

For best results, set controls to;
Fan speed ---- Any setting except "OFF"
Temperature----Towards WARM (red zone)
Air intake ---- FRESH (outside air)
Air flow ---- FLOOR
Air conditioning ---- OFF

For quick heating, select recirculated air for a few minutes. To keep the windows from fogging, select fresh after the vehicle has been warmed.

Press the "A/C" button on for dehumidified heating.

Choose floor/windshield air flow to heat the voltage interior while defrosting or defogging the windshield.

AIR CONDITIONING

For best results, set controls to;

Fan speed --- Any setting except 'OFF"
Temperature --- Towards COLD (blue zone)
Air intake --- (outside air)
Air flow --- PANEL
Air conditioning --- ON

For quick cooling, move the air intake selector to recirculate for a few minutes.

VENTILATION

For best results, set controls to;

Fan speed --- Any setting except 'OFF"
Temperature --- Towards COLD (blue zone)
Air intake --- (outside air)
Air flow --- PANEL
Air conditioning --- ON

DEFOGGING

The inside of the windshield

For best results, set controls to:

Fan speed --- Any setting except 'OFF"
Temperature --- Towards WARM (red zone) to heat; COLD (blue zone) to cool
Air intake --- FRESH (outside air)
Air flow --- WINDSHIELD
Air conditioning --- ON

The outside of the windshield

For best results, set controls to:

Fan speed --- Any setting except 'OFF"
Temperature --- Towards WARM (red zone)
Air intake --- FRESH (outside air)
Air flow --- WINDSHIELD
Air conditioning --- OFF

On humid days, do not blow cold air on the windshield. The windshield could fog up because of the difference in air temperature on the inside and outside of the windshield.

DEFROSTING

The outside of the windshield

For best results, set controls to:

Fan speed --- Any setting except 'OFF"
Temperature --- Towards WARM (red zone)
Air intake --- FRESH (outside air)
Air flow --- WINDSHIELD
Air conditioning --- OFF

To heat the vehicle interior while defrosting the windshield, choose floor/windshield air flow.

2001 chevrolet tahoe secondary air system not working cant pass smog all I did was replace battery before getting it smog


Disconnecting the battery resets the PCM - engine computer ,an the emission monitors . A drive cycle has to be done to get the monitors to run an hopefully set. That's all you need to do is drive it for few days of different driving conditions - city , highway ,from cold start . google GM drive cycle . OBD Monitor Not Ready

Replaced battery on 2006 murano and now display for radio, air, etc does not come on


According to the owners manual - -
To turn on the screen, push the "SETTING", trip
control, air conditioner (except rear window defroster
button) or audio button.

There's nothing in the book about special instructions should the battery be disconnected, so if the screen will not come on I would guess a fuse or something happened to the power source.

Radio not working


I believe the Kia has 2 fuses for the radio, one in the cabin, and one in the engine compartment. Check them both. If they are good, your radio is toast.
