SOURCE: 2003 chevy tahoe no rear heat

I know the earlier tahoe's have two heater lines running from the engine compartment to the rear under the vechile. Those lines could be clogged or pinched shut. What you do is get two hose locking pliers. Go under your truck, they are two metal lines that turn into rubber and back into metal again farther down the line. First, checked for pinched lines. If none, find where the rubber hoses are, clamp them off, remove from metal lines and drain. Use garden hose to flush fresh water through. When water comes through at high pressure and pretty clear, it should be done. Reconnect hoses, top off radiator fluid and it should be fine.

SOURCE: Air conditioner/heater blower fan on 1997 Buick

it will be hard to diagnose with out having my hands on it but try this.

this vehicle is known for blower motor resistor failure.

under the dash on the passenger side next to the blower motor there is a resistor attatched to the blower motor case it will have a single plug with 5 or 6 wires in it, they are normally within a couple of inches of the blower motor, remove this resistor and look at closely for any signs of burning this is a common problem, you can buy one at any parts house, do not operate the motor with the resistor removed from its mounting hole or you will damage it.

if the resistor looks good than purchase you a test light and drop me a line and i will explain how to test the entire system its not hard to do.

Im trying to locate the fuse for the rear blower in my 2008 gmc arcadia, can anyone help me


RR/HVAC fuse 30amp located in the under hood fuse box. You can check it but highly doubt it's the problem . More then like it's the blower motor control module that's bad .
Circuit/System Description
The auxiliary blower motor is a variable speed fan. The HVAC control module controls the fan speed by sending a pulse width modulated signal to the auxiliary blower motor control module. The auxiliary blower motor control module varies the duty cycle across the auxiliary blower motor in relation to the pulse width modulated signal. The auxiliary blower motor speed can be adjusted from 10 percent to 90 percent duty cycle (PWM), 90 percent is high speed fan.
Watch this video for testing purpose's only , this is a front blower motor control module . Same way your back one works . GM is GM Chevy , Buick ,GMC , Cadillac .

My 2005 gmc yukon rear a/c or heat blower will not come on front a/c and heat work well


{: ) If the front a/c and heater is working fine, that's good. At least the problem can be isolated on the rear HVAC circuits only.
Check first the RR HVAC fuse 30amp at the underhood fuseblock and the IGN 3 fuse 10amp at the IP fuseblock. If you found them good, then you can begin diagnosing the blower circuits wirings and connectors.
A faulty blower definitely will not give any output. If it doesn't spin for some reason, rear a/c or heating cannot be circulated.
A faulty blower resistor or speed control processor can also cause a zero air output. Sometimes, the blower may only work at certain speeds only.
A faulty rear HVAC control switch may not give the proper signals to the blower resistor or speed controller, and in turn will render the blower motor disabled.
Sometimes it can be a terminal connector being loose or burnt. However, the most usual cause for this type of problem is a faulty blower resistor.

2001 Tahoe..the front a/c works great...the rear a/c doesn't blow at all...thanks!


Have you checked the fuse yet? If not, the fuse you are needing to look at is located in the fuse panel located under the hood inside the engine compartment. It will be the fuse marked "RR HVAC"
Below is a picture of the location of the fuse panel and a picture of the layout of the fuses. Maybe it was just me but it took me awhile to find that fuse so I want to give you a lttile head start as to its location in the panel. It's a little to the right of the center towards the top. I hope this helps and good luck.

Got a 207 chevy tahoe ltz--rear air works ---front air does not work. any suggestions?


"2007 chevy tahoe ltz--rear air works ---front air does not work." Hi! I guess you are referring to the front hvac blower not blowing air at any speed and not coming out at any vents at any mode position. If this is the case, you can start with the fuses at the underhood fuseblock. Check out the three hvac labeled fuses. If found okay, and the hvac controller on your dashboard seemed to be working normally, you better check out your front hvac blower motor underneath the right IP section. You need to verify if power is reaching your front hvac blower when requested by the a/c blower controller. I hope you get lucky. If this is not for you, perhaps a few more detailed symptoms would be helpful. : )

it sounds like you have a crappy connection on the rear blower. i think your blower is on the right side rear. remove the panels and the blower is right in your face. check for voltage and repair the messed up connection.
