      Members Only Fluid Forum View   08/08/2017

      Fluid forum view allows members only to get right to the meat of this community; the topics. You can toggle between your preferred forum view just below to the left on the main forum entrance. You will see three icons. Try them out and see what you prefer.   Fluid view allows you, if you are a signed up member, to see the newest topic posts in either all forums (select none or all) or in just your favorite forums (select the ones you want to see when you come to Fishing Minnesota). It keeps and in real time with respect to Topic posts and lets YOU SELECT YOUR FAVORITE FORUMS. It can make things fun and easy. This is especially true for less experienced visitors raised on social media. If you, as a members want more specific topics, you can even select a single forum to view. Let us take a look at fluid view in action. We will then break it down and explain how it works in more detail.   The video shows the topic list and the forum filter box. As you can see, it is easy to change the topic list by changing the selected forums. This view replaces the traditional list of categories and forums.   Of course, members only can change the view to better suit your way of browsing.   You will notice a “grid” option. We have moved the grid forum theme setting into the main forum settings. This makes it an option for members only to choose. This screenshot also shows the removal of the forum breadcrumb in fluid view mode. Fluid view remembers your last forum selection so you don’t lose your place when you go back to the listing. The benefit of this feature is easy to see. It removes a potential barrier of entry for members only. It puts the spotlight on topics themselves, and not the hierarchical forum structure. You as a member will enjoy viewing many forums at once and switching between them without leaving the page. We hope that fluid view, the new functionality is an asset that you enjoy .

2001 Dodge Grand Caravan A/C fan issues

Recommended Posts

Last year I had my a/c pump freeze up so I got it replaced only to find out that the reason it failed is because the cooling fan doesn't turn on. The shop said that the fan is bad and the relay is bad. So I am going to replace them both myself and bring it in to get it flushed.

So here's my problem. I have 2 fans and I'm not sure which one runs the a/c. Drivers or passengers?

Also, how do I get to the relay? I read that it's under the headlight but I took out the headlight and couldn't see anything.

I'd appreciate any help you can give.

Thanks

I would realy hesitate on replacing both the relay and fans. If the fan is bad usually it will lock up or you will find the plastic fan plastic melted where it burns to the motor. The relay is under the lt headlight and the front of the grill has to be loosened up. Look at the wiring, I've repair a few of them. Also there was a recall on some of the vehicles with rear air the a/c compressor and lines due to metal getting into the system.

ok, I wondered about that too. The shop said it was bad but I was going to check it first. Both fans move freely and there is no sign of melting. I would like it very much if I didn't have to replace it.

Which headlight is the relay under? If someone has a more detail about getting that out I would appreciate it. I lose the wiring around the headlight.

Thanks again

When I took out the headlight the area is pretty much all enclosed in sheet metal. Do I need to take that out somehow?

you need to remove the bumper cover (at least disconnect all the fasteners on the top side and pull it back) to gain access. It will be in the area under the drivers headlight but not literally under it. It will be riveted to the unibody. It sounds like you have the new part so you should be able to recognize the old one when you see it.

The older models had them bolted to the driver front lower frame rail near the lower radiator support. They where a real treat to replace.

One other thought is that you can disconnect the fan and jump it directly to the battery. This will allow you to see if it runs and listen to it to see if it makes any noise. Use some heavier wire if you attempt this. If the fan works than your on the right track with the solid state relay.

No, two different systems. The fans should work regardless of the condition of the a/c and the a/c will try to work regardless if the fan is working.

Which leads me to another question do the fans turn on at all? Is the vehicle overheating?

Funny you should mention that. I just got back from picking it up because it overheated this morning. It never has before. Come to think of it, I don't think I've ever heard the fans come on and I've owned it for 6 years.

Does the relay operate both fans?

Yes it does.

Basically there are four wires going to it.

Orange w/Red is the 12 volt power from the fuse

Dark Blue w/Dark Green is the power to the fans

Black w/Dark green is the ground for the relay and fans

Dark Blue w/Violet is the PCM control

Hey guys,

Thanks to both of you for all of your help! I was able to find it (it wasn't nearly as hard as I was making it) and replace it easily. I also found out that the fans were perfectly fine but the fuse had blown. I sure am glad I didn't them to replace the fans! Anyways, it works good and I appreciate your help!

    • The only thing to use them for, If I had one!  
    • Utube Randy Newberg spring bear hunts. He has a ton of DIY info on spring bear hunting
    • I've never used electric jacks, or hydro. I've heard they are pretty nice, and guys like them. It will be interesting to see how you feel about them after a season or two. I'd like to hear your input on them after you've used them awhile.
    • Yes, out of 100lb logs so they can't carry it away!
    • Really ufatz, that's how tomorrow  will affect fishing?? It all depends on what your fishing for. If I'm just off the flats chasing walleyes it would be interesting to see if they work there way up on top mid day. Probably not. To much of a short window.. 
    • Are fuses necessary on an on board charger?  Manual chargers do not have them,  is there a reason for them on the on board charges. I was given a system with a bank that may not have been working correctly, possibly blowing the fuse repeatedly.  My system would not be hooked up to an alternator on the engine so I'm wondering if it is fine to use the charging bank without the fuses.  The orange charging light comes on when I hook the wires directly up to a battery. I'm asking because I don't want to go through the bother of wiring this thing in my boat if I can't get it to work right. Also, I would technically only need 2 of the 3 banks to work, but I like the idea of repairing it to its potential.
    • My bait is getting hit but the bear does not like the large, cinnamon gum drops i added to the bait! He will drag them out and move on to other tasty treats. I do have red licorice to add next time.
    • Thanks...  Only truck in our neighborhood anyway....
    • Better than breaking your arse slipping on the ice.  
    • Yes!  There is no question the eclipse will affect fishing! The eclipse will draw peoples attention away from fishing and the casual angler will be all wound up about watching the event. They will not be paying attention to anything else and surely not to fishing. The result will be far fewer anglers on the stream and YOU will have more room to fish and less competition. THAT is how the eclipse will affect fishing.
