Caravan/Voyager Heating/Cooling Problems



  • masterpaul1masterpaul1 Posts: 421
    Hi All and Happy Fathers Day. The weirdest thing happened last night while driving home from work. I was driving all but 15 min. with the air on, then all of a sudden, all the squares lit-up for the gear selection, the air bag light came on and the air was warm blowing out of the vents. I thought that maybe the engine cut off, but it didn't, so I kept driving. I tried turning off the blower but it wouldn't turn off. So, I though to stop and turn off the engine. After I did that everything went back to normal. I drove for about an hour today and didn't have any problems.

    Was just wondering if anyone else experienced this and if this is a sign of a bigger problem down the road? Thanks

    1999 Dodge Grand Caravan with 3.8 engine. Radiator and a/c fans inop. Replacement of relay located below air filter did not fix. Where is the sending unit located on the engine that controls this system? I found the one for the coolant temperature gauge and the one for oil pressure but can't find the above one. Thanks for your help.

    I have a 1996 VW jetta that I top up the freon every year on to get the air conditioning working. I just this week put some in but I'm afraid I put too much . It was supposed to be 800 grams of freon and I put 1000 grams. The compressure still works but I don't get any cold air coming out the vents. Could I have damaged something permently? can I take some out? if so do I take it out from the high or low side of the system?

    I would be thankful for any help
  • Hi, I have a 1998 Plymouth Grand Voyager, I just bought it in February 2009. I have been using my a/c and using it properly, turning it off before I turn off the vehicle. Things like that, I have had enough vehicles with a/c units that go out and no money to fix the problem. However, I have small children and live in Sacramento CA. I need an a/c. Today when I left my house I used my air like I normally do, however, when I got to my mom's house 3 miles away. I turned off the car, got out and heard some bubbling sounds. Then I called my husband at work told him what was happening. Put water in the coolant resourvor. Just like he told me. I left my mom's house about an hour later and turned on the a/c however it was only blowing out hot air. I took it to a place that I thought could recharge it and it would be fine. He told me that neither of the fans are turning on. I called Kragen's they said it might be a relay, but I don't know how to check those and my husband isn't quit sure either. They also said to check the fuses which my husband is going to do later today when he gets off work. I'm not sure what's going on with the air, but I am open to suggestions. Please email me and let me know if you have heard of this problem or you have had it.

    If the fans are not coming on, then the van will be prone to overheating - especially at low speeds or idle. The relays and fuses are located in the power distribution center, which is just to the right (looking at the van) of the battery. Inside the lid of the PDC is a diagram that labels each of the fuses and relays (the relays are the black boxes). If you pick up a Haynes manual, it will show you the testing procedure (I have done it, but cannot remember which prong did what and therefore do not want to steer you astray). You will need a multimeter and a set of alligator clips.

    If the relay is fine, check the connection on the fans themselves to make sure it is getting power.

  • I have a 1998 Plymouth Grand Voyager where the interior heating is inconsistent. It alternates between hot and cold and is usually turns warmer when stepping on the gas. The engine temperature is consistent/normal as the vehicle operates.

    Any suggestions would be appreciated as the temperature in Wisconsin and inside the van reaches is a chilly 30 degrees.

    It sounds like you have a bad coolant thermostat.

    the only way to get the compressor to come on is to unplug the switch on top of drier for 5sec plug it back in the clutch engages when it cycles you do the same thing ive already replaced the switch does anyone have suggestions
  • I can change the speed of the air (low to high) but I can not change the direction of the air flow ie upper vents, lower vents, lower/upper vents, defrost. I can not get recirculate to come on. I can not get heat to come through. The air that does come through the vents is outside temperature. I can turn the a/c button on but it doesn't "kick on". Any suggestions on how to fix this. I have no money to spend at a repair shop. This wouldn't be a problem with winter coming except for the kids need a heater. Please help

    Bought this van this summer, made sure all the fluids were topped off and A/C seemed to work fine. With the colder weather we have realized the drivers side vents will not put out any heat. It has the climate control zones for rear, driver and passenger so initially I thought some damper somewhere probably was stuck closed for the driver side but since air comes out just fine I realized that probably isn't the case. Anyone know the basic T/S steps I should take? Are there relays or fuses? Does that fan on the drivers side direct/collect heat to feed the drivers side vents? Noticed radiator fluid was low so made sure to get that topped back off.

    Any ideas would be great.
