Question about Chevrolet Traverse

1 Answer

Heat will only work periodically

When we are running the vehicle we will get periodic blasts of cold air and then will switch between defrost and "feet" and will get heat on one and then cool. When we switch back we will get heat for awhile and then cold. I've read it might be fluid levels but am not able to check until tonight. Thermostat seems ok because the car warms up to "normal" temp while running. Thanks!

Definitely check your antifreeze/coolant level ASAP.

SOURCE: 2001 pt cruiser no heat

did you check the fluid level by removing the rad. cap? Radiator should be full to top. If Chryslers are low on coolant, the heater will not blow warm air.

Try changing the lower temp sensor in the air duct on the drivers side. I bought one and never replaced it. before the part arrived I took the lower sensor out and taped it up and put it back under the dash... not in the air duct housing were it belongs. believe it or not it works so well I did not even see a need to change the thing.

I would have the cooling fan checked, and have the thermostat changed. An overheated thermostat (overheating caused by something else) will cause problems in the future.

I recently replaced the thermostat water pump No blown head gaskets on my 01 Aztec SUV but its still running hot what could be the problem


If you do not have "good heat" coming from the heater there is a very good chance you have an air pocket trapped within the engine.If this is the case, try to get the front of the vehicle elevated as high as possible (a small hill works and air will travel to the highest point) with radiator cap removed,heat turned to the warmest selection on defrost.Periodically revving the engine then letting it idle,then turn the vehicle off listening for the gurgling(or strange noises,which is actually the air escaping to the highest point :) it may take several attemps,but in the end it works.

Heatdoesn't work, A/C blows out warm air and defrosts blow out cold air


Right think the problem is the heater core is blocked with corrosion ,now remove the bottom hose from the rad and the heater hoses then flush every which way you can including through the heater core reversing direction then ,refit all the hoses fill with water only and see if heater works if so the remove the bottom hose again and drain ,then add a minium of 3 litres of antifreeze ,its a anti corrosion agent as well as antifreeze and without it the internal of the engine will corrode and the slurry will block the heater first then the radiator ,

What is the drive cycle for a 1999 vw jetta


The drive cycle is as follows
For all OBD2 VW's

OBD-II Drive Cycle Stages
The OBD-II Drive Cycle is an eight-stage course, as illustrated in the
chart on page 3. An explanation of each step is provided below.
Stage 1: Cold Start-The ECM determines the presence of a cold start
by comparing the engine coolant temperature to the ambient air
temperature during startup. The engine is considered cold when:
• Engine coolant temperature is below 122°F (50°C).
• Engine coolant and intake air temperatures are within 11°F (6°C) of
each other at startup.
During this period, the O2S heater, misfire, AIR, fuel system, and EVAP
monitors run.

Stage 2: Idle 2½ Minutes-Turn the air conditioning (A/C) and
headlights on to help the misfire monitor-the additional electrical loads
help even out combustion pulses. During this period, the O2S heater,
AIR, EVAP, misfire, and possibly fuel system (if operating in closed loop)
monitors run.

Stage 3: Accelerate-Prior to accelerating, turn off the A/C and
headlights (if possible). Open the throttle halfway until you reach
55 MPH (89 KPH). During acceleration, the misfire, fuel system, and
EVAP monitors run.

Stage 4: Steady State Cruise-During this portion of the cycle, the
O2S, AIR, EGR, EVAP, misfire, and fuel system monitors run.

Stage 5: Decelerate-Gradually coast down without applying the
brakes. Also, on manual transmission vehicles, remain in high gear and
do not press the clutch. During this period, the EGR, EVAP, and fuel
system monitors run.

Stage 6: Accelerate-Apply ¾ throttle until reaching 60 MPH (97 KPH).
During acceleration, the misfire, fuel system, and EVAP monitors run.

Stage 7: Steady State Cruise-During this period, the CAT, O2S, AIR,
EGR, EVAP, misfire, and fuel system monitors run.

Stage 8: Decelerate-Gradually coast down without applying the
brakes. Also, on manual transmission vehicles, remain in high gear and
do not press the clutch. During this portion of the Drive Cycle, the EGR,
EVAP, and fuel system monitors run.

You can try this a couple times, but if it doesn't work you should go to a VW specialty shop like the dealer or a shop that does mostly European cars and they can use the scan tool to force the car through readiness.

Air/heat blower is not working unless it is on high.


The heater resistor is probably faulty, its located near the blower fan

Ridiculous the heat doesnt work


First, check to make sure the coolant level is full...if not, it will bypass the heater core. Next, try replacing the thermostat and radiator cap. These are both inexpensive, and it's a good idea to replace them periodically. Finally, you may need to replace your heater core. Unless you are mechanically inclined, this is something best left to a mechanic. The difficulty of changing this ranges from vehicle to vehicle.

No heat, have replace theromastate is working


sounds like you have an air lock in the system,when the car is cold remove the coolant cap,start the car and let it run with the defrost only on full blast this will allow any air in the cooling system to escape through the open radiator cap,and it will also spill some coolant that is normal,just refill when you are done.

Changed the thermostat, still no heat. Is there a valve of some sort in the heater hose lines or on the heater assembly that controls the hot water?


when the vehicle is cold take the radiator cap off and start the vehicle let it run with it on defrost at full blast until the vehicle gets to running temp,if there is still air in the system it will blow cold air if that doesn't work then check to see if the vacuum lines that run the blend door in the heater box have came off (depending on year)

I just bought a 1992 Izuzu Trooper, yesterday the heat was working fine....lastnight we started to get a winter storm so by this morning there were at least 4in of snow and a temp of 13 degrees. I warmed...


You may have a frozen heater core.

Drain the cooling system and remove the lines that run from the engine to the vehicle's metal firewall, attempt to blow compressed air through the lines. DO NOT allow the core to pressurize more than 14-20 PSI, as damage can occur.

If the core is frozen, it can be thawed by warming the vehicle's interior to room temperature and maintaining it, although this method will take several hours. You can periodically test the heater core for flow by either introducing water flow or using compressed air. You can also just blow in the line, but please don't let your mouth make contact with the coolant line. Use something between your mouth and the line, so you don't ingest coolant.

Overheating in 2002 sedona


To check if it is the thermostat run the car and when the temp starts going up turn the heat on full blast in the car. If the temp goes down after you turn the heat on than it is your thermostat.
