I found this URL on internet http://www.chefseattle.com/blog/site-news/suburban-rear-liftgate-wont-unlock-how-to-fix/ If your vehicle is similiar maybe it can help.

My 2005 tahoe did the same thing. I also bought a new motor, which did not fix. I discovered there was a bad ground. Instead of searching for bad ground, just install a short length of stranded wire with crimp terminals between a wiper motor mounting bolt and a rear glass latch assy mounting bolt to restore good grounding to the wiper motor.

It is most likely not the blower motor. Intermittent operation usually means the blower relay is failing. It should be under the hood in the main fuse box. Try that before you spend a ton of money on bigger parts. Hope this helps. Good luck.

well it cant get much easier, just unbolt them and bolt in the new ones.

Appears that there is a relay in the system as well, so check & swap same number relay if you can, i'll dig a little deeper in meantime.

Notorious for plugged heater cores. Also updated plastic restriction couplers mounted at heater core available from dealer. Try back flushing heater core. Run engine till its at operating temperature then carefully hold the inlet and outlet hose breifly with heater fan on high if hoses are nearly the same temp then flow is good , if not then core is plugged.

I have the same problem with my 2001 Tahoe. The front blower is working, its blowing strong, but its cold air even with the temp setting as high as it can get. The rear blows hot air. The engine temp guage is at about 210ish which is close to being normal (220). I just replaced the thermostate a few months ago, I don't know if its bad again, or it I deluted the antifreeze too much and it frooze the heater core, or if the heater core just went bad. Any one know what the cause could be?
