Question about 2005 Dodge Magnum

1 Answer

Engine overheats in idle

I don't think either of the fans are working. Could it be a fuse or relay? If so, where do I find it under the hood?

    What exactly do you mean by overheat? does gauge go to hot, or light go on? do the fans ever come on? Look for air bleeds...

Why won't my cooling fan turn on (swapped thermostat, thermoswitch, fan really)(fans work when hard wired to battery). Causes car to overheat in idle.

depending on the year, there should be 3 relays that control the fans.
There's a rad fan relay (4 pins), an a/c condensor fan relay (4 pins), and a fan control relay (5 pins). This allows them to be run at low speed or high speed. Check the grounds behind/under the righthand headlamp.
Check Fuses 57, 58 (30 Amps) and fuse 46 (15A) under the hood, and fuse 3 (7.5 Amps) in the driver's underdash fusebox.

Radiator fans are not working on 2009 Toyota Camry 4 cyclinder. A/C compressor cuts off while idling, and dashboard temperature gauge shows a hot temperature when idling but not when moving. Is it likely...

Dear An,
You have two different systems, but since you car is "newer", they are made to try to help each other if there is a problem.
Let's address the "overheat" problem first, then go to the A/C.
A good mechanic can check the electric engine-cooling-fan for function by "hot-wiring " it.
That fan is actuated by an engine temperature sensor that screws into the engine block.
These sensors can fail, as can the next item in the circuit, which is a relay, usually found in the black plastic box under the hood.
One of those two items should be the cause of the overheat, the way you have described it.
Sensors cost roughly $20 at a car parts store, as do these relays.
The reason the A/C shuts off is likely to prevent overheating at a stop light,
God bless your efforts.

Engine fan not working

Could be low on coolant, the cooling fan motor, a relay, or the fuse among other things.
A mechanic would check for power at the fan motor after checking the fuse.
Is the check engine light on ?

I have a 1999 chrysler 300m and the ac fuse relay keeps blowing

If your 30 AMP fuse for the fan is blowing and your AC does not work, it may be that your Passenger side fan stopped working. The problem is, then , that you may overheat quickly. This 30 Amp fuse is located under the hood in the fuse box, and is clearly marked on the cover. These are not cheap fuses, and if they blow they will indicate a serious issue, so don't just replace the fuse. With the engine off, and the key in your pocket and the engine being cold, reach down to the fan and give it a spin. Check BOTH fans for spin. If they make a rough squeeking noise or will not spin at all, then it is very likely the fan making the nosie or not spinning is the culpret and has to be replaced. It makes dollar sense to replace them BOTH as an assy, since they have the samer milage on them, (Dollar-wide it is more cost effective and less of a pain to replace. If you need details on how to remove the electric fan assy, just hollar back and we can line it out for you. (It's not as bad as you might think).

Where is location of cooling fan relay?

Under the hood on the drivers side, just forward of the shock tower, you will see what is called an "under hood fuse center". On the cover you can see the various fuses and relays that are located in the fuse center.
One of those relays is the coolant fan relay. Remove the top cover of the fuse center to gain access to the relay.
Hope this answers your question, good luck.
