    I think i will start from checking the refrigerant pressure first, easiest and cheapest to rectify the issues before i move on to the larger problem.

    Thanks,

    I had similar problems with my car ( another model) , guy in service told me, that this is alternator problems. I had to buy another alternator on boodmo.com . Good , that problem solved after that. I was afraid that I was wasting my money.

    Strangely enough, when i was using AC at level 3 fan speed, the A/C works just fine, the A/C slow working happens at level 1 and 2 fan speed. Guess i just need to crank up the fan speed at 3 and drive it for few weeks before do anything.

    Thanks,
    Ken

    My BLM sometimes wont run at all if i put to fan speed 3 or 4. But this is due to that speed is rarely used almost to the point of never used and most probably the contact point in the switch is corroded or not contacting properly.

    Got one time the connector on the circuit board in the aircond control panel is broken and i had so improvise by soldering wire directly to the board, i had to dismantle the blower fan speed coz its in the way. After reinstall, need to wiggle the switch when using speed 2 or 3 if the aircond refuses to switch on..Now everythin is working fine.

    That is interesting, because the fan switch when on, just activate the compressor, so is funny you say run better at higher fan speed. Maybe higher fan speed you feel the cool air so think is running better?

    Hi,

    Not quite, when on speed 3, i can hear the compressor working like on time before the freon ran out. Like i said the timing is accurate when the compressor kicks in. According to the aircond guy who modded the a/c system of my E46, the timing can be adjusted somehow, though i don't know how is it being adjusted?

    Thanks,
    Ken

    That timing thing is something new. I only know there is air con switch and fan switch. Both need to be on the activate the air con system. Fan on, air con off get fan air only. Anyway get yours checked and inform us what was wrong, need new input......:driver:

    Dude's finally got back to me, he is referring to the thermostat settings, too high, the compressor won't work, too low, the compressor work's too damn much and burn out the clutch. My situation now may due to slightly high thermostat settings.

    Anyone can back this statement up?

    Thanks,
    Ken

    Thermostat then correct, but even if low or high setting, the moment the car starts, compressor should engage because have not reach the settings yet. Hotter setting it will cut off faster, maximum cold setting then it will work most of the time

    Then i will ask them to adjust slightly colder settings, normally i like drive with 2 speed fan only at 20 degrees.

    Thanks,

    I know this thread is already for quite some time. just looking for existing thread to ask about maintenance free battery (so called dry cell battery).

    recently i see in facebook a mechanic share that maintenance free battery actually has the water inside. just peel off the sticker on top, use coin to open the + cap, and refill the water inside. this will make battery last longer, some said up to 4 years.

    i know the part that even maintenance free battery has water inside, but topping it up, never think of doing it. so what the difference between maintenance free and not? is it just simply maintenance free one use better electrodes/material inside?

    please share your experience/thoughts. thanks...

    Dry cell car battery has "lead" and rods in it to generate electricity. Maintenance free battery generally do not require any maintenance done to it, just occasionally check and ensure the power indicator is green at all time and no visible leaks from the battery. Battery life also depends on your car's electrical charging system (alternator), grounding and stability of the overall electricity supplies to your car's accessories. It's no rocket science, all batteries need to be replaced in between 2-3 years depending on how you use the car.

    Thank,
    Ken

    Basically the batteries are the same, only MF battery have a different top. According to what I read, the system trap and condense the water vapor, therefore need less maintenance.However it still need ventilation, so will still loose some water. I have switch back to non MF battery since I find they last about the same time. If your batteries are not over charged, even non MF battery don't need to add water. What I find is usually at the end of it's life, it loose more water.
    Another thing is to heat shield your battery for longer life....

    Heat shield meaning keeping away excessive heat to the battery?

    Yup, like some the battery are place right behind the radiator fan, as in my Chery SUV. My Mitsu one at the side so one piece of aluminum board can do the trick. Chery one I cover all round.....lol

    Shield L shape corner to corner. This battery dated 1/2014, upon checking was changed in 6/2017, so lasted 3 and a half years. Currently still running on the changed one so is 2 years already....
