My 2002 Chrysler Town&Country van has an extra humming sound in the morning when I start driving.?

Unfortunately that is one of those problems that has to be heard by a mechanic when the car is cold. He could then put a mechanic type of stethoscope on parts and listen to isolate the noise when it's happening.

Drop the van off to your mechanic in the evening and have him check for the humming in the morning after it sits in his yard overnight.

humming could be numerous things

wheel bearing starting to go

idler bearing on serpentine belt

low power steering fluid

etc

check all fluid levels..especially transmission....transmissions can act funny when cold, especially with low f or dirty fluid

take it to a local mechanic before its warmed up

were is the humming coming from. next time get out and listen to where it is coming form or the area it is loudest at. to pin point it. it will give people a better idea. just saying extra humming doesn't really help much.
