The first thing to check is the door seals if the car is not equipped with a sun roof. The next thing would be the seals at the windows, top bottom and sides. Is the door filling up with water? There should be a drain hole in the bottom of the doors. I think. Also, outside the car at the base of the windshield there should be a grill. Sometimes debris will clog the drain for it. Sometimes you can get in the car and have someone squirt a water hose at the car and you ean inspect for water entering the car. I had the same problem with mine...It was under the windsheild, remove the grill and seal around the wiper arms and look for anything else that might need sealing since you're there. Check your fender wells for rust through. That was what I found on my 1994 LeSabre.
The transmission is not shifting in and out of gear or your front joint is going bad
I would say that you are losing coolant somewhere hoses,water pump,radiator.
I'm not sure, but it may be time to have the transmission serviced.
Try changeing the fuel filter,I had the same problem and it helped.
A lack of oil in the engine./ the sensor in the oil system./ broken oil pump
Likely the blower motor is bad, causing increased current and blowing the fuse. Replace the blower motor.
it sounds like a steady bearing on the drive train or pssibly your tourque converter is going bad
Sounds like a torque converter issue, have it checked at a transmission shop
It could be a vacuum leak. Check all those air hoses in there. It's a good idea to replace them every few years or so.
Bad/sticky thermostat.Cooling fan(s) malfunction.Bad head gasket.Cracked head.
Underneath near radiator. There is a nipple with a black plastic cover. I recommend accessing this from under the vehicle if hot. The exhaust manifold could cause burns if accessed from above.
