01 durango blinkers not working

Sounds like the ignition switch. It is a very common problem for those vehicles.

This sounds like the ignition switch needs to be replaced. These are very typical symptoms of a common problem in these vehicles. It is probably not related to anything you did, but be sure you don't have a lot of weight hanging from your keyring.

Sounds like you have a dodgy connection in stereo's wiring if it works sometimes. Hope this helps.

The battery might be low but I doubt it is causing the "no idle" problem.
You should have an idle air control valve that the computer uses to adjust idle speed. That valve could be faulty or dirty.
Is the check engine light on when the engine is running ?

most of the time when the blinkers are not working and have checked everthing its most likely the switch itself get u a hanes bookthey help out alot when having trouble

i would check the turn signal lever switch in the steering column.

that vehicle has a desperate relay for the hazards which is why they work, you have a defective signal flasher sometimes called a signal relay, follow the noise to locate exactly where the part is, usually under driver side of dash, it is a very cheap part and easy to install.

Your blinker switch is broken and needs to be replaced. you can pick one up , but putting it in wont be that easy. you will need a puller set and some other tools. take it easy on the next one because you wouldn't want to fix more than once. take care and good luck.

i had the same problem in my 2003 Durango!!
turns out the auxiliary fan was not working!!
that fan should run all the time when the a/c is on!!
so start the truck, turn the a/c on and then go look at the aux fan (the plastic electric one attached to the radiator) and make sure it is spinning!!

With the key OFF, turn on parking lamps and emergency flashers. Then walk around the entire car, looking for lamps changing brilliance. Any that DON'T change brilliance either have a bad bulb or a bad ground connection!
