Question about Buick Cars & Trucks

Open Question

2004 Buick Regal failed inspection in Sept. due to water leak in module which had to be replaced to pass inspection. Since then I now have water sloshing in dash but not leaking onto floorboard. Is

When module was replaced, the suspect seemed to be the vinyl boot that seals the windshield upon manufacture of automobile. It seemed logical that rainwater had gotten down into dash and found its way into module under passenger seat. The heat and humidity was suspect in the warping. It has since been sealed off temporarily with duck tape and is as tight now as when tape was put on immediately following module fix. Tape was temporary fix until money became available to order and install new vinyl boot. I drove 12 hours to NY during the nor'easter and encountered constant rain and downpours. I now have this water in my dash and it only started after that trip to NY in October. I am almost afraid to drive it for fear it will just quit after shorting out all the electronics in the dash. Please help.

SOURCE: Rain water leak

Yes Ive had this happen to my Toyota corrola and my dodge there are 2 different reasons why this is happening 1 of them it depends on if you have a sun/moon roof if so theres a vent in there so if any water or anything goes in it reroutes it too the outside of the car if its cloggeed water will spill into the car like that and just leave puddles the second thing is if you have it parked outside with trees all around theres vents up on the hood where the windsheild meets the hood they clog up so if you look along the back firewall which is under the hood all the way in the back theres a hole that gets clogged you need to clean that out and the easiest way to do that is get someone with a air compressor and blow air in that holke to push it all out it should fix all your water problems and if you have any questions let me know ill be glad to help, also please rate me.

SOURCE: fluid leaking onto the front passenger side floorboards.

2004 TB 60,000 miles. i was just told that the leaking fluid in my passenger side floorboard was do to a clogged up A/c hose. An A/C works by drying/ removing the moisture from the air inside the vehicle and cooling it. The accumulated fluid is usually evacuated under the vehicle which is what you see when people are stopped at a red light and there is dripping under their car. when a hose is blocked there is a vent that from some reason flows directly into the passenger side floor board. If you can not manually knock loose the block your probably going to have to take it to a mechanic.

SOURCE: Have a leak under passenger side dash when it rains. I think the door under the cabin air filter isnt closing is it an easy fix

Having just repaired this problem in a 1998 Buick Regal, I can tell you that fixing the water leak is actually quite easy. It took me quite a while to track down the source of water, but I have discovered that it comes through the cabin air filter. There is a seal on the passenger side of the cowl (A two piece unit, black plastic, against the windshield) that seals it to the windshield to prevent water infiltration. It is very small and somewhat hard to miss. I took the cowl off to change the filter when I discovered this.

You can make a diverter to go over the air filter under the cowl, or even easier is to use some clear RTV silicone (avalible at any automotive and most hardware stores) and put a good bead on the old seal. When you re-install the plastic cowl, be carefull where it goes against the windshield to make sure you don't "smear" the silicone. After you re-install the plastic retainer hardware, smooth out the bead and clean up the excess silicone(a wet finger and some old cardboard works great). Let it dry and clean up the water in the passenger compartment.

Cleaning up the water is the hard part. Removing the plastic trim around the door (if you grasp the trip peices firmly they just pull up off some metal clips,but they can be quite stubborn) you will notice the carpet just pulls up. At the bottom front corner of the front doors the carpet has a plastic hook that is around one of the trim clips. Lift it off that and the rest of the carpet towards the firewall just pulls up. If it has been a long problem, your carpet may be moldy. Also, the carpet edges and some of the more hidden panel clips are very sharp and may cut you while you are poking around, so be carefull.

Since the water entered through the air filter and right over the fan, you will at minimum want to replace the filter. I had mold and moss growing on mine. My fan also squeels and chirps now, so I know it got wet. Not much to do about that but replace it or carefully lubricate the motor.

In your question you mentioned a door underneath the filter not closing. On my '98 Buick Regal there is no door or valve of any sort. The filter sits right above the fan blades. It is the cowel's job to prevent water from entering this part of the vehicle. I hope this helps you fix your problem.

What cause my 1995 buick regal to jerk at 55 just before passing gear,i do have a leak in front tranmission line would that be it

Stop any oil leaks as the transmission requires exacting oil pressure to do the job. Any leaks reduces the pressure so gear changing is affected. Besides when do you know if the oil level has dropped below operating level and will be insufficient for the gear box.

On my 2004 buick regal my number 6 cylinder mis fires i have replaced sparkpluge and wire sill misfire y is his

Spark Plugs should be replaced every 3 years,
in my world

Wires are only replaced after ten years or more, or when they
fail, on a secondary ignition test,not just so you can be sold
something called a tune-up that really is non existant

Plugs seldom misfire,they just wear down & stress the ignition

A misfire is caused by ignition coils,modules,vacuum leaks,
egr & such

Just have to go thru all the scan tool data at a repair shop &
on a road test, then component test or look for the obvious

My 98 buick regal looses coolant I have recently flushed system out, replaced water pump & thermostat but my I keep loosing coolant dont see any leaks i will fill it up & in a couple of days its...

Take look down by the belt tensioner. There are two by-pass tubes that run from the tensioner to the engine. The by-pass elbows have rubber seals on them and after the coolant flush may have damaged or ruined the seals.
The only other option is the coolant is going into the engine oil or transmission oil. Check both oils and see if they look "milky"
Good luck.

Why do my fog lamps fill with water on 2003 buick regal

Hi, the reason your fog lamps is filling up with water is that the seal between the outer lense and the backing part has failed, now their is no way of repairing this as once the water gets in its to difficult to get out and seal again.
The only option you have is to buy new fog lamps they are not expensive to buy and are easy to replace.

What causes them to leak like this is when they get hot and cold due to the sun being on them this causes the plastic to stretch and then shrink when it cools again, this then causes the bonding between the two halves to fail allowing any condensation and water to form inside the fog lamp.
Failing to change these lights could cause the electrics to short out and then this could cause problems with the fuses and wires in the car so changing this as soon as you can to prevent further damage to your car.
