#11 of 50 Re: car overheating, radiator fan is not working [phatbecker] by tsteele6 Aug 19, 2005 (10:18 am)
Replying to: phatbecker (Aug 14, 2005 3:36 pm) I have a 1997 Neon. When I got it the fans would not work either. There is a small Mopar relay mounted (oddly) underneath the battery tray. For some reason, this fails reliably. It costs around $80 from Dodge, but I found it on Ebay for $32. Search on Ebay for "dodge fan relay" and it is the only thing that comes up. The relay is used on many Dodge models. Plug it in and the problem will be fixed.
#12 of 50 Hello again with bad news by shymerm8 Aug 17, 2005 (3:29 pm)
Okay I am back                       Once again with bad news thanks to whoever said my overheating problem was my head gasket You were right however I wish it was a lot simpler for the dealership to find out the problem. The termostate we replaced I'm sure was a good idea to do however, the car kept overheating even afterwards and losing power. The engine light would come on and then turn it self off so there was no proof there was a problem with it losing power. Then by some miracle the light stayed on the other day, so back to the shop it went. So we had them retest why it was overheating and a losing power. The chrysler dealer said it was a fan module, and there was oil in our spark plugs. They wanted 550.00 for the fan and 800.00 for the spark plug replacement. I did not have them do the work because well it was a lot of money that I could not afford since this car breaks down all the time, it does not allow me to save for the next breaking down lolol. My friend looked at the car, and checked the spark plugs they were dry as a bone, and surprise no oil at all. Then he told me to take it to a friends shop were they have the machine that tests it to see what is wrong. Then my friend would do the work since he works on dodges.Well it is my head gasket not the other things the dealer told us. I was wondering for months where my antifreeze has been going since I had to fill it up all the time. I just don't understand why the dealer could not tell me the real problem instead of making one up ? It just seems weird for my head gasket to be blown, a cam sensor go out, a speed sensor go out, power steering pump to go, 2 windows go out, a door, having to replace all my freeze plugs already, my motor mounts go, and I just had my spark plug done lol 15,000 miles ago and they are saying it is my spark plugs again lolol is this normal for it to be in the shop every 3 months when my car just turned 3 years old with only 90,000 mikes on it. I just cannot keep up. It has truly been a nightmare between the car breaking down and the poooooooooor customer service I recieve at these dodge and chryser dealers. I am sure I might have missed other things that have gone out that I cannot remember because it is to painful to remember lololol. Oh yes to the person who told me not judge dodge/ chrysler on my neon well I don't have to too, I can base my expereince on their customer service too it stinks. I will not do business with this company again. However my new car is great and it is not a dodge lolol                 Shyleen
#13 of 50 Many Questions by swimguy195 Sep 03, 2005 (4:14 pm)
Alright, where to start. I just recently bought a 95 Dodge Neon with overheating problems and seriously underpowered. I buy cars a fix them, that's why I got it. Anyways I tracked down my problem to replacing the Headgasket and cleaning the head. When for a first test drive after finishing up. Everything seems fine except the engine is a bit noiser than I expected and makes an odd hard to describe noise. Is this normal for a Neon? I also got a Check battery light. I couldn't find anything wrong though. Today I do a longer test drive. I start having problems. The Engine overheats and I find the radiator fans aren't running like they should, also my temperature gauge is stuck on overheat. Sounds like an electrical problem to me somewhere. Any ideas on where to look? Replies to this message: davidd5 (Sep 04, 2005 1:22 pm) swimguy195 (Sep 05, 2005 12:19 pm)

Replying to: swimguy195 (Sep 03, 2005 4:14 pm) Doing a diag on an engine noise over the internet is very hard to do. Some Neons have a piston slap noise that will go away when the enine warms up. When you did the head gasket,did you have the battery tray removed? If so,you may have forgot to plug in the battery temp sensor on the bottom of the tray. This will turn on the charge/battery light. What do you mean by "the rad fans are not running like they should.? Are they running at all? Are you sure you have a enough coolant and do not have an air lock. Can you jump the rad fan relay to make sure the fans turn on? Replies to this message: swimguy195 (Sep 05, 2005 12:19 pm)

Replying to: davidd5 (Sep 04, 2005 1:22 pm) The noise seems to stay even when I get it warmed up. The battery Tray stayed in place the whole time. The radiator fans where not working at all when the car overheated, but once it cooled they worked again. Fan Relay works fine, one of the first things I checked. I'm sure that's there's plenty of coolant and no air lock. I may have foudn the problem. I exaimed the wiring harness and found along it that the wires where fused to together from some intense heat. I dissected the area and so far have not seen and insulation away from the wire, so I have to keep looking.

#19 of 50 Thought this was fixed? by planetmf Nov 17, 2005 (12:53 pm)
I always swore nobody could give me a Chrysler product. Well, it just so happened that a 2000 Neon came my way for a good price. Same year as my Elantra with a fraction of the miles (42,000). Don't you know a couple of days after I brought it home I noticed a good sized spot of coolant underneath it. Dodge dealer where the car originally came from replaces the radiator cap. Still leaked. The second time they say nothing is wrong and charge us 60 bucks to put dye in the system. So now my spot is neon green. Took it to a private garage and he tells me it's the HEAD GASKET. I researched before I bought this thing and thought Dodge had this resolved. Any action I can take here? Should have listened to myself I guess.

Replying to: planetmf (Nov 17, 2005 12:53 pm) I bought my 98 Neon Expresso Sedan new in 97, consider me a very happy owner. Have only suffered a few problems, the first was the head gasket when the vehicle was less than 5 months old - dealer replaced the head and have not had any problems since. I do believe that this should have been a recall issue though, fortunately my vehicle was garage parked so I noticed the drips of oil early on. The second, has to do with the power moon roof. It had been replaced twice while on warranty because of the rails and recently has gotten stuck again ( I have been told that to replace it now, they won't repair it, will cost me just under $1000), it cost me $100 to have them close the moonroof and I am not planning on having it replaced. The only other issue I have had in the 8 years and 140,000 miles of owning my vehicle is the problem of draining the battery. With no warning the battery will be drained. This began right after the warranty expired (approx. 4+ yrs, 60K miles), now I find I have to replace the battery about every 9 months. I always have the diagnostic run and everything is fine. So, I don't know what causes this. Due to this I always buy the warranty on the battery and keep my roadside assistance current. Though recently, a disquieting incident occurred which I am inclined to believe had something to do with the battery issue. One rainy afternoon about a month ago (early November), on my commute home from work, my rear windshield imploded unexpectedly. I didn't know what had happened and called 911. The police after responding believed that having my rear window defrost on had over heated the back window and caused the implosion. When I had the window replaced the installer, with my only telling him of the implosion, had agreed with the Police that he believed it was a power surge and that he sees it fairly often. Didn't think at the time to ask if it was specific to Neons. Anyway, now I use the rear window defrost sparingly and am just glad that it occurred after I was off the highway and driving slowly in a residential area. Other than these problems have only had to replace tires and windshield wipers and brakes once, everything else is original.
