I have a 1995 Blazer 4x4 with the Vortec, and AC, and I think my blower motor is going out. I have replaced the switch, and it is working for now, but I have a feeling the motor is what might be bad now. IF it is the blower motor, where is it located? I see an enclosure around where the AC stuff goes into the firewall, is that where it is? Do you access if from there, or do you have to go behind the glove box? What is the easierst method of swapping this? Or is it better left to a shop? PITA or not?
pita-did one on a 96 last saturday. Unsure of your skills but... I'd recommend a Haynes or Chilton/GM book and even those are a pita but.. (poor-incomplete info). Also don't know how many funds you have or if you've got an honest skilled mechanic. It is diy dooable and you will possibly even see links or info on the web without buying a manual(if you don't have one already). Plus-I, based on the degree on difficulty, would'nt do it until your other one goes. My customer with his 96 had it last almost a year after the initial noise started.

I appreciate the quick response! So where do you access it from, behind the glove box?? Skill wise, I know enough to be dangerous when it comes to this, that's about it. I will most likely just take to a shop, but I figured with book time rates exceeding $60 bucks an hour, I might try it myself... What did you pay for the motor you did on the 96? Just curious.
Doug, I could be off-base here but as I recall, on the 95s specifically, you need to **cut** the blower motor housing along a dotted line to access the motor. You then need to **glue** or **screw** that piece back on. I don't see the logic of designing something this way other than the fact that it makes for a nice airtight seal. That being said, the plastic on my blower housing is so brittle I can break into it by hand... Good luck! Andrew.

I bought an AC Delco motor because in the past I've had issues with the volume of air the aftermarket units provide. I've also been using AC Delco units for quite a few years-no problems. Now some bad news- they have a list price of about $120.00 US dollars-I'm not at liberty to discuss 'cost' here but you may get a discount off that price. I'm sure the aftermarket is cheaper but sometimes cheaper is not better. Here's a phrase I picked up on this site: Good parts aren't cheap and cheap parts aren't good! Anyhow if you want a fun project go ahead. BTY why do you feel you need a blower motor but if you do the coolant jug comes off(you can unbolt it and swing it into the engine center compartment-leaving the hose hooked up) as well as make sure you unhook your negative batttery terminal. The computer will have to come out(be cautious). There will now be a loom of various wires that have to be unhooked and moved to the side. This will reveal the location of the heater motor. Another word of advise-if your motor & %*ts the bed or is quite intermittant, you, before all this, can unplug your old one and temporarily plug in the new one in your hand and CAREFULLY have an assistant turn it on and try all speeds. Hold it tight-if only 2 speed work I'd bet your problem is the resistor- which is one of the two problems we had with that 96 Saturday. Once all those wires are moved enough,(not alot be cautious) now where marked, you'll have to take a utility knive and cit where GM has marked and remove the outer plastic shell(that may break all to pieces as did the one I did Saturday) This plastic cover removal will now reveal the heater motor. It'll be held in place with 6-7 quater inch/ 7-32nds bolts. If memory serves me correct there may have even been 5 of one and two of the other.(nice-and a couple are dandys to get at-in fact when the motor is completely 'free', you'll still have a fun job getting it out of there-use care as you put it back in.) Replacement is reverse of removal. Simple! I can't tell you what your time or satisfaction in doing a job is worth but...if you had an honest mechanic and he quoted-oh well I can't make this decision. If you do it allow atleast a couple of hours of your day for this project(possibly more depending on many factors) Good luck-keep us posted because we love to here about fun jobs where the manufacturer designed something as fun as this to do! jerry@peru-motors!
