2005 Dodge Grand Caravan is making a squeaking and like ticking noise, after it warms up some it quits, What could this be?

if its a ticking noise then its probably a lifter noise from age and mileage or none scheduled maintenance. on your next oil change you can try running an oil system cleaner through your engine but this is not something to be overly concerned about.

Squeaking noise? Have belts adjusted or replaced.

try thicker oil or more oil. that might help

It's one of the pulleys that needs to have the bearing replaced most likely. Check for wobbling pulleys where ever the belt makes contact.

I would have a repair shop, put an oscilloscope
as well as a stethoscope
on the motor, to tell you the answer

Nothing to do with dirt

Most likely they never use their scope for that,
but that is were we are at with todays cars

If you spend nine grand ,you may as well
learn to us it

How about the belt tensioner? Have you checked it out?

The Sway Bar LInks are common to squeak.

SOUNDS LIKE YOU HAVE STICKY LASH ADJUSTER(LIFTER)..MANY MILES ON IT?HAVE YOU BEEN GOOD TO CHANGE OIL AND FILTER?TRY CHANGING THE OIL AND FILTER AND ADDING AN OIL SUPPLEMENT ..IF THIS DOESN'T WORK,YOU WILL HAVE TO ISOLATE WHICH BANK OF ENGINE NOISE IS COMING FROM,REMOVE VALVE COVER AND YOU CAN TO SEE WHICH ONE(S) ARE MAKING NOISE..PUSH DOWN ON EACH ROCKER ARM..A BAD ONE WILL BE SOFT..A GOOD ONE WILL BE HARD..NO LASH..TO REPLACE..YOU REMOVE ROCKER SHAFT BOLTS AND ROCKER SHAFTS..YOU CAN PURCHASE ONLY THE ONE(S) YOU NEED..BE CAREFUL WHEN YOU REMOVE ROCKER SHAFTS..THE LIFTERS CAN FALL OUT..GET A STICKY GREASE TO HOLD THEM IN ROCKER ARMS DURING REASSEMBLY..I HOPE THIS HELPS

the door lock actuator is going bad.

the flasher is under the dash on the drivers side that is definitely a possibility but it also could be a multifunction switch
