I tried to do a transmission flush on my 2001 buick regal ls using just jugs of water to see if anything is clogged. I poured about 5 jugs of water into the radiatr and everything flowed out fine and fast, but when I poured it into the part where the thermostat goes it flowed out slow. Could that part be cloged up? If so when I take it to the shop to get a real tranmission flush will that make it flow properly?

SOURCE: No heat, when I turn on heater- all cold air flows out

sounds like you have a stuck blend door in the HVAC system. If its not controled by vacuum the servo motor is bad or the vacuum line is bad. This door moves back and forth to go from vent to floor to defrost. and you have one to go from cold side to hot side. Hope this helps you

SOURCE: fans run constantly

Irwinr12 is right, no amount of fan will keep the Regal from warming up if the thermostat is working properly, Replace it. Clear SES light with OBDII tool & you should be good to go. BTY its the car computer that keeps the fans running, and they will continue to run until you clear the code. Any kind of cooling/overheating proiblem will kick in the SES light and set both fans running. I own '01 GS, my son has '03 GS and we have both complete set of service manuals. Trust me, do what I say. Batman

SOURCE: where is mass air flow senser on a 1989 buick

Hi

Thanks for using FixYa. The BUICK Regal Mass Air Flow sensor is usually installed in the intake air duct between the air filter and the throttle body mounted on the intake manifold. Also check the throttle body for mass air flow sensors location.
On mass air flow sensors with a sense wire, this wire can become contaminated with dust particles. These particles can be removed with automotive solvents that are safe for the use on mass air flow sensors. Before replacing the mass air flow sensor check for air leaks in the connecting air ducts and intake manifold. These leaks can cause similar symptoms as a malfunctioning mass air flow sensor.

Bad or contaminated BUICK Regal Mass Air Flow sensor can possibly cause a wide range of various vehicle drivability problems such as stalling, especially when the engine is cold, misfiring, poor acceleration, etc. In addition, a problem with the Mass Air Flow sensor often causes the "check engine" or "service engine soon" light in the vehicle instrument panel to illuminate.

Please do accept the solution if the issue is resolved or else revert for further assistance.

Thanks
