Default water flowing sound from stop to go

I got my car back from the body shop. I just noticed that there is a little water flowing sound when the car goes from stop to go. The car was in the body shop for a month, before that I didn't hear that sound. Do you guys have that experience?

"Maybe" it's a clogged condensate drain preventing the pan from draining. Turn on the AC and see if there is condensate dripping on the ground...... If not, the drain tube is clogged.
Where is the sloshing sound coming from?

I will check ac drain. The water flowing sound feels like come from front passenger side near the vent

Is is it possible body shop screw up something when they fix my deer damages? They replaced the front left upper panel, left headlight and front bumper

The noise appears to be the AC drain. Am I missing something? The deer damage is on the right side of the vehicle. Can you post before- and after- pictures from the same angle? Would be nice to see one pair that is head-on view.

After the car is stopped on brake, I can still hear a little bit water flowing sound from front passenger side near the vent. Sound is not loud, but you can hear it if it is quiet.

Was there any mechanical damage from the accident? Was there coolant loss? If so perhaps when they repaired the cooling system leak, they didn't bleed it properly and there's an air pocket in the system. That would definitely cause a water flowing sound. I'd check your coolant level.

And if they replaced your front bumper, headlights, etc...there's a chance your radiator has been replaced, or at least damaged as well (causing a loss of coolant).

no mechanical damage from the hit. It is 30mile per hour hit on a deer, deer ran away.

Insurance paper say only replace right upper panel, whole headlight, bumper

the body shop did open up my front passenger side door to adjust the window as a favour because the glass tilted forward a little bit when closing

how do I check the drain and how do I undrain it if there is water?

Get under the car on the passenger side and look for a hanging hose, that will be the drain tube. Take some compressed air and blow into the hose....... wear safety glasses and be prepared for some leaking water. I have also used a piece of #12 solid wire to slide into the tube (rotor-rooter) but most of the time I use air.
Run the car with the AC on (outside air in) and flush out the pan...... You should see the condensate dripping on the ground.

Where is the sloshing sound coming from?
outside temperatures is 53f, lower than temperature ac can set. I turned the ac on for more than 10 mins, no water dripping underneath

i didn't hear water flowing sound when I swing front passenger side door. If there is water, should I hear the sound when swinging the door?
