2005 dodge van makes a chirping sound - 2005 Dodge Grand Caravan

If is a serpentine belt, take it out and check the belt tensioner. some of them have a screw that allows for tightening/loosing the belt. Sometimes it looses some bearings and it could chirp.

check your brakes, the worn brake indicators make a chirping sound

this sounds like it could be a worn/loose belt,weak belt tensioner or timing belt maybe loose or need replacing.

alternator bad??? causing a drained battery

dry u joint change them all because if ones gone the others will soon follow.

Check your coolant fan for proper operation.

sounds like your lifters

A slight squeel when starting is most likely a loose belt which just needs tightening up. If it was the pulley the sound would not stop.

Check to be sure there is the correct amount of preload on the front wheel bearings. Too loose or too tight will give you strange noises. Also, you may have a calibur hanging up or retracting too slowly. It causes the brake pad to stay in "Light" contact with the rotor and cause noises too. This could be an intermitten problem.

Good Luck

Same problem here

I tried to re--enable my keyless entry transmitters but no luck. When I press the unlock/lock button, the van chirps but not locking. Even the manual button in the van doesn't work.
What is the problem and how do I fix it?
