SOURCE: stalls when warm , no start when warm
What you need to do is when it stalls out then check to see if your loosing fuel or spark.Check for spark at the spark plugs.don`t just check one.Check all the front 3 a least.If no spark then you probably have a bad ignition module.It is under the coils.Good luck.
SOURCE: '02 Buick LaSabre. heater blowing
hi, some cars have a HEATER FLAP. if not CLOSING then cold air will be blown in. LEAVE ENGINE OFF and check the lever and listen for the SLAP of the flap CLOSING. the control cable is faulty. or the ELECTRONIC HEATER CONTROL NOT WORKING or the HEATER RADIATOR (UNDER DASH is BLOCKED). or AIR in SYSTEM. needs bleeding. gerry
SOURCE: First thing that started the outside temperature
That is two separate problems. The "Flickering" of the outside temperature thermometer might be normal to some extent. Sometimes, the voltage from the sensor is at a point where it could be say, 31 degrees F or 32 degrees F. The display may flicker back and forth between 31 and 32 very rapidly until the voltage changes just enough to go make it go solid one way or the other. It probably does this all the time, but you didn't notice until you were paying attention to the temperature problems inside the car. (One actually has absolutely nothing to do with the other.)
The cracking and popping noises you are hearing from the temperature door and the difference between the temperature on the driver's side and the passenger side are the same problem. Apparently, you have dual zone climate control. This is usually caused by one of the temperature doors sticking and either stripping the gears inside the door control actuator or breaking the door itself. If you have both sides set at "HOT", the side that is cold is your problem-child. This will usually also set a fault code in your climate control module and may make your climate control display flash. (but it doesn't always flash when there is a code present)
SOURCE: Heater on and working -
one of two things could be happening... either the radiator is low on coolant or your thermostat is stuck (which if it is stuck you will have to replace) . But first let engine cool down, you need to check coolant level, squeeze one of the radiator hoses even if engine is cooled down to make sure there is little or no pressure in cooling system then remove radiator cap/coolant bottle cap to check level.by the way if it is low you will need to figure out why.. the obvious reason is a leak you may have to go to a shop and have system pressure tested to locate leak to repair.. good luck to ya.. hope this helps

Faulty coolant temperature sensor and a faulty heater control valve.
This means that the engine's PCM detected that the engine has not reached the required temperature level within a specified amount of time after starting the engine. The intent of the P0128 code is to indicate a faulty thermostat. Similar codes: P0125
In determining the engine did not reach a "normal" temperature, it takes into account the length of time the vehicle has been running, the intake air temperature (IAT) sensor reading, the engine coolant temperature (ECT) sensor reading, and the speed of the vehicle.
A code P0128 may mean that one or more of the following has happened:
Past experience indicates that the most likely solution is to replace the thermostat. However here are some suggestions on troubleshooting and repairing a P0128 OBD-II code:
