'94 Voyager, no air conditioning

Discussion in 'Voyager' started by Mike De Petris, Apr 3, 2005.

  1. The air does not come cold, the light glows on the button but the air is at
    external temperature.

    Already checked all fuses but I can't find in the manual wich fues or other
    connection I should check, what else?

    When you press the air button does the compressor actually cycle on? If not
    may be low on R-134 or some other issue.

    I have to check, but I am new to this car, got it in december and stayed at
    repairing in the last month, so I am not sue of which is the compressor and
    where to find it, it is not marked in the manual.

    I generally encourage the do-it-yourself option when possible, but if you
    honestly are not sure of what an AC Compressor even looks like you may want
    to stop where you are or get a friend that is knowledgeable. AC can be
    dangerous if you are not sure what you are doing.

    AC compressor is front top. You should be able to watch it with AC off and
    see the drive pulley turning, while the outer part, the clutch is not
    turning. Have someone turn on the AC. The clutch should emit a loud clack,
    the engine will drag slightly (can usually be heard even from inside the
    van) and the clutch portion should lock in and turn with the drive section.

    A quick test to confirm if it is low pressure in the system is to remove the
    connector from the low pressure cut-off switch and put a jumper on it. Have
    someone turn on the AC while watching the clutch again. If it starts now you
    are low on pressure. Don't let it run more than just a few seconds with no
    pressure in it.

    You need to go to a repair shop. They will most likely tell you you
    need an evaporator. It is an expensive repair, so get ready.

    Just curious why you feel they will "most likely tell you need an
    evaporator"?
    I am currently on my 4th Caravan since 86, all have been well over 150k
    miles on them and none ever needed an evaporator replaced.

    Starting in 1994 with R134a freon, Chrysler evaporators started failing
    left and right. I noticed the biggest problem with the LH body, but it
    seemed no model was immune from it. And yes, specifically I have fixed
    a number of 94-95 Chrysler minivans with failed evaps. I don't know
    about after the body change in 1996.

    If this is my problem, what do you suggest to be sure it is fixed in a way
    that doesn't brake again for the same reason?

    When I was replaceing them years ago, I tried the aftermarket and they
    only had reboxed OEM cores at the time. I don'r know if you could get
    an updated part now. Even a poor quality evap core that holds pressure
    out of the box will probably get you to the point where you will sell
    or junk the van, so I wouldn't worry about it.
