Question about 2001 Chevrolet Tracker

1 Answer

I have no heat in my 2001 tracker. The thermostat is brand new and the switches and controls on the inside are funtioning properly.

The thermostat is new, and the climate control switches are functioning properly but I'm getting no heat out of the vents.

    yes the blower is working fine and the blend door is functioning properly too. The controls are also switching the blower from floor to vent to defrost as they should as well.

    Your heater core is bad since everything else is good.

SOURCE: There is no air flow

You need part GM Part number 89018675 or ACDelco 15-73596. The Mode Selector Actuator. What happens is the part is a CHEAP part POORLY designed and when it goes to turn the flaps inside the HVAC unit its the plastic gear slips instead of turning the flap!!!

Just to forward you you might want a deal to install this art for you unless your good at fixing your own vehicle, because you need SMALL sockets and a lot of patience to get this part in!!!

The part is ALMOST directly above the steering shaft for your steering wheel, so theres a lot you got to remove before you will even see them!!!

I only recommend you to have a dealer put this part in for you, unless you have your own service manual!!

Because there is 5 of these darn things and if you pick the wrong one you will have to do it all over again!!!

3 on the Drivers side and 2 on the Passengers side!!

But replacing this part SHOULD solve all your problems!! AS it did for me and i was having the same issues as you have described!!

The problem is a 1/8 diameter hose that runs from the front of the engine over the top and connects at the rear of engine on the drivers side. It is a vacuum hose #GM15967970 It cost about $6.22 at your GM dealer. Hope this helps Bill. My E-Mail is
This was posted on a problem with a 2002 astro, I do believe it is the same fix. A simple vacuum hose, It is difficult to route through the engine

SOURCE: heater control 98 chevy s10 blazer

These trucks have a problem where moisture builds up in the heater box then freezes. When this freezes and you change your heater settings it breaks the shaft for the blend door. If this is what happened you should be able to look under the dash above and to the right of the gas pedal and you will see two vaccuum accuators one of them you should be able to wiggle around the linkage if it is broke. To fix this you need to remove the entire dash to get the heater box out which involves discharging the AC and draining the coolant because the heater core and evaporator come out. Please rate.

SOURCE: climate control not working

I had the same problem on my 2004 GMC Yukon XL.
Still under warranty the shop was able to reprogram the climate control system and tell what was wrong rather quickly with a OBD computer.
That’s when they found both of the climate control (driver and passenger) side actuators were bad and the control unit that tells the actuators where they should be was also bad.
The truck was in the shop with most all the dash, seats, consol, and steering wheel out for a week. The cost was over $1200.00.
That has seamed to fix the problem. Good Luck.

SOURCE: 2003 Trailblazer No air from front face vents

first check to see if you have power going to the actuators when you switch the switch to it location if no power replace controller if you have power and no movement from actuators replace actuator. if actuators move remove hvac box and check for broken blend doors.

Heater in 2001 chevy tracker blows cold. when i switch from a/c(blue)to heat(red)i do not hear the (thud) like before. how do i repair myself? my mom is disabled & little $

You must remove the entire dash assembly to cure this problem. The cold air and no switch to heated air is a broken air temperature control bleed door is my opinion and most likely right.

Heater blowing cold air and engine overheating for 2002 Dodge Intrepid

first check engine coolant levels, add if low, secondly, check waterpump for proper funtioning, then if the vents are still cold, start looking at the heater hoses for issues and ther is a control valve that lets hot fluid enter the car..if this is locked or stuck you should be able to move the lever by hand and see if it works.. its normally vaccuum operated..good luck

Heat is not very hot

Try replacing you thermostat. If this does not function properly the engine will not warm up enough to produce sufficient heat inside the car.

It only heats well when were driving if you are stopped at a light or in traffic it starts blowing cool air

Probably needs a new thermostat.

If you replace this yourself, open drain on radiator to remove the current coolant. If you can't find a drain, loosen clamp on the radiator end of the lower hose and drain. Don't forget to re-tighten the clamp!

Be sure to catch the drained coolant for proper disposal. Some types are poisonous to animals, so be sure to protect your pets by following proper disposal procedures.

Once drained, remove bolts on thermostat housing, remove old thermostat (taking care to notice its orientation in housing), clean the gasket mating surfaces, install the new thermostat (taking care to properly orient in housing), put on new gasket and reverse removal steps. Don't overtighten bolts on the thermostat housing, as it's possible to break the housing if too much torque is applied

Be sure to evacuate any trapped air in the systems so as to get proper cooling effect.

A model specific repair manual should show the location of air bleed ports (if any). Older vehicles tend to not be as difficult to properly eliminate any trapped air as newer vehicles. Your '01 Tracker probably has at least 1 bleeder port.

After installation, run engine until thermostat fully opens, then add coolant as required to fill. Once the thermostat opens and coolant starts to circulate, the level previously established in the radiator is likely to drop.

Additionally, it's a good idea to give another coolant level check after the engine has completely cooled down and the expansion effect of heat has ceased. If equipped with a coolant recovery tank, make sure it is filled to the proper level as noted by the fill marking on the plastic tank.

Also be sure that you have adequate antifreeze protection.

Generally a 50 / 50 mixture will provide adequate protection against freezeup. This depends, to some extent, on the general winter temps in your home area. Obviously, if the temperature can routinely go below 0 degrees, you need even greater antifreeze protection.

Hope this helps!

Over heating, i tried a new thurostat but did not help the over heating,

clogged radiator? bad water pump...cooling systems are quite simple...water circulates through the engine under the force of the pump...even if the thermostat is working it still needs the pump to move the water...still have the old thermostat? put it in a pot of cold water on the stove and turn on the burner...see if it opens at the proper temp setting...if the old one does you dd not need a new one..oh, I have installed brand new thermostats that were bad...

Have you tried replacing the rad cap ? or leaving the rad cap off while running your vehicle for a while to ensure that their is no air locks in the coolant system?

Should change drivers front switch. If neither rears work and main switch don operate them then it is the drivers control that is bad.

Heater Not Working

Do you mean the fan does not work or the fan blows but there is no heat ? If you mean the blower, check the resistor at the wiring just before you get to the blower.The resistor is a small gadget. Not to be confused with an electronic resistor. If the blower works but there is no heat, replace the thermostat.
