1995 Suburban Front Blower Inop

I have a 1995 Chevy Suburban 1500, 4WD Auto with buckets. The middle and rear ac/htr blowers work, but not the front.? I believe there are separate blower motors for each? Does the 1995 have a relay similar to the 2005 on the website? Any help will be appreciated. Thanks.

The relay and resistor for your truck are separate parts and yes, there are two different blower motors. The relay for the blower is behind the glove box area and on top of the heater-a/c case. It should have five wires attached to it. There should be battery power at all times on the red wire, ground at all times on the black wire, the orange wire should have battery power with the key on and the blower switch on high, the blue wire should have varying power on all speeds except high and the purple wire should have varying voltage with the key on and the blower switch in any position except off. Check for power on the purple wire at the blower motor with the key on and the blower switch in all positions and ground must be constant on the black wire at the blower motor. If both are present the blower motor is faulty. Try bumping the motor if power and ground are present to see if you can temporarily reset the brushes in the motor. Please let me know if you need any more help.
