What is the reason for water leakage in the Jetta driver's side during rain?

Introduction to the reasons for water leakage in the Jetta driver's side during rain: The reason for water leakage in the driver's side during rain may be due to damage to the rubber seal on the driver's door. Rubber seals are rubber products, and rubber products can age over time with prolonged use, leading to water leakage during rain. There are many sealing rubber strips on the car doors and trunk lid, which prevent rainwater from entering the trunk and interior during rain. Here are the measures to address water leakage in the driver's side during rain: 1. If there is water leakage in the driver's side during rain, the main repair process involves removing the accumulated water inside the car: There are several rubber plugs located at the bottom of the vehicle chassis. Opening these plugs can drain the accumulated water inside the cabin. However, since the interior carpet materials absorb water strongly, the carpet should be removed and placed in a spacious area to facilitate water evaporation. After reinstallation, it is also important to turn on the air conditioning and set the vehicle's circulation switch to internal circulation, allowing the water vapor inside the cabin to be expelled through the air conditioning system. This is a very quick dehumidification method during summer. 2. If the damage caused by water leakage in the driver's compartment is significant: It is best to contact your car insurance provider immediately (within 24 hours), clearly explaining the cause of the water leakage and the extent of the damage to the insurance company's customer service personnel. Inquire whether a claim can be filed. Under unclear circumstances, never start the engine, as this may result in losing the opportunity to file a claim.
Water leakage into the Jetta's driver side during rain is a common issue with a few typical causes: The door's weatherstripping may have aged or cracked, allowing water to seep through gaps during heavy rain—check for any visible cracks by running your fingers along the seals. Another possibility is a clogged sunroof drain tube; accumulated leaves and debris can block drainage, causing water to drip from the headliner onto the driver's seat. Failed window seal gaskets may also let water trickle down the door frame into the cabin. Additionally, blocked body drainage holes can cause rainwater to pool and backflow inside. Prioritize inspecting these areas, especially on older models where seals tend to brittle—replacing them promptly prevents worsening damage. Water intrusion is serious; soaked carpets risk electrical corrosion, short circuits, or musty odors. Act quickly: diagnose the issue yourself or visit a trusted repair shop immediately to avoid long-term damage.
Having driven a Jetta for years, I personally experienced water leakage into the driver's compartment during rain. It turned out the drainage channel under the windshield was clogged with debris, causing rainwater to flow in along the A-pillar. Additionally, the drain holes at the bottom of the doors were blocked, trapping water that eventually flooded the cabin. A word of caution: sunroofs can also be problematic due to occasionally flawed drainage tube designs—regularly flush them with a soft hose. Also, check for rust holes in the floor pan, as they worsen water seepage. I resolved my issue by manually clearing the drainage channel, but I recommend inspecting seals and drains during every car wash—prevention beats repairs. Water intrusion risks damaging seats or electronics, compromising safety.
Water leakage into the driver's seat during rain? Possible causes include: poor door sealing allowing rainwater to seep in from the edges; clogged sunroof drainage causing water to enter the interior; leaking air conditioning intake ducts affecting the area around the driver's seat. It's not difficult to check - just inspect these points for any abnormalities.
