Check the fan resistor bank, it's in the air ductwork under the dash, on the passenger side, by the blower motor. The fan resistor is used to allow the 12volt dc motor to have multiple speeds, and run slower than the full 12volts. The output of the fan squirrel cage typically blows right across the reistors to keep them cool.
 
Follow the wires from the fan motor, they will plug into the resistor bank.

It is probly just a bad fan motor. Easy fix under the dash on the right side by the passanger side. Three nuts and remove from housing and order new one put back in. Unsually comes with the squirrel cage if not remove off old moter and install.

1995 GMC SUB 4x4 will not start by acehi

The problem I'm having, it will start sometimes and at other times it will not turn over at all. The battery and cables are good. The dash has all of its lights. With the head lights turned on while I try to start it, don't even dim. I have changed out the safety neu. switch at the tranny (advice from a friend), it help so I thought for about a month. Today I went out to start it and its back to the same old problem, turn the key and nothing happens. What do I need to do to fix it. I'm pretty good at turning a wrench. Thanks for you help. Tony

May be a solenoid/starter problem.
 
To avoid just throwing parts at this problem, I would hang a fused test lead off of the starter solenoid (the power coming from ignition switch), to see if the solenoid is being told to engage.
 
If you are experiencing the problem, and you turn the ignition switch and see power going to the solenoid, and the solenoid doesn't engage and turn the engine...then you've proved it's a solenoid/starter problem.
 
If on the other hand, you have no power being supplied, then you know the problem is 'upstream' of the starter, for instance possibly the ignition switch itself.

'89 Sub. rearend problem! by mudrat

I have a '89 GMC Sub. , 350ci, 4in. Skyjacker lift, 4.10s front and back. 12 bolt in back and 10 bolt in front. The lift, the gears and the axles have been under the truck for almost 35k miles. Detroit locker in rear. At least it did. It just blew out. The entire axle casing is shot. It blew out thru the cover and the bottom of the housing. Looks like the locker blew apart. It was not under pressure or off-roading. Just got inspected and going for a test drive. BANG. What rear axle will fit and what will be strong. I do a fair amount of off-roading, but not serious. I also plow snow. Since I'm going to replace the whole axle, what should I use?

96 suburban climate control problems by crjones231
Nov 04, 2008 (12:20 pm)

My 96 GMC C1500 2WD Suburban is doing weird things. It has 200,700 miles on it and a dual system climate control. The front AC works fine but the heater does not work (it just blows air). In the back the heater works but the AC does not. This is what I have checked so far in front. Both accurate work, but I don't know if the actual blender damper is working. I have check the fuses, electrical connections, vacuum connection, and water leaks and they all seem to be OK. I think it might be the heater control valve but I'm not sure so, I thought I would ask if anyone else has had this problem before I start throwing money at it. Any thoughts?

by chance did you check to see if you may have a blockage somewhere from water pump heater connection to heater core an sometimes the core can be block to from old coolant, it brakes down in to a solid, had this happen to me. and you have to check both suppy and return hoses for this and if none of these then last thing i say is one of your vaccum doors under dash vent system is not working.and for my problem for all the people out there who have 90 subarbans check wireing main harness i back of engine they have some wires with a tape around the connections that wheres away with time that is one of reasons your engine my run like its out of time or you my be burning rich from to much fuel.
