My 2002 Durango radio goes into seek mode and stays there. Is the radio bad or is there another problem

the capacitors may be worn--grap ahold of it and see if bettr recept--cud hav a bad connect too

replace the transmission control module

This means its in scan mode, it will go through all station until you stop it,make sure the scan button is not stuck, try to turn radio on and use the manual scan and dont use the seek button,

the blower resistor goes bad ,its upside down by the blower motor ,part at pepboys about 25.00 time to replace about 20minutes 2 bolts and 1plug it pushes up in the lower duc work its very easy to replace

your transmission is in safe mode this will need to be scand to see where the problom is in the transmission

I would go for the belt tensioner first

take the plastic thing off that goes all the way around the guages or w.e. then ther should b 2 bolts on the front of the stereo take them out. take out the radio n unconnect wires. then get a wire kit n plug it in and hook it up. if the speakers dont work either get new ones or rewire them using all different wires.

You can try disconnecting the negative battery cable for 5 minutes and see if that will return the radio to the factory default setting. If you have steeing wheel controls, there is a possibility the seek button on the steering wheel is bad or the wire from the steering wheel to the radio. If that checks ok, then the radio has an internal defect and will have to be replaced.
Good luck.

You can buy adaptor plugs that allow a simple hook up at most car stereo places.  However, when you increase the power going to the speakers you also have to replace the speakers to handle the higher power or you'll toast them.
