96 Blazer

idrd on Mon May 18, 2009 2:38 AM User is offline

Year: 1996
Make: Chevy
Model: Blazer
Engine Size: 4.3

Going to replace the Compressor, Dryer, Evap, hoses and condenser, well, the entire system.

Bought the truck when it was two years old for my son for college. When he finished I decided to keep it as I love the thing. Compressor went out while he was in school in Nebraska and not really sure what else they replaced. Around 2002 the intake gasket leaked and replaced engine,also done in Nebraska. I live down here in Phoenix.

Since the day we got it back from getting the engine put in, A/C has never been right. While son had it in Nebraska, they just kept recharging it. Had it charged again about a month ago, and it lasted two weeks and bang, no more cool air. I can see the green dye stuff that was put in it on the top of the compressor. I have not problem replacing it as its time, as a matter of fact the reason I am wanting to change everything is my other son gets his permit in Jan. and I will give him this car.

This is my question on the Evaporator. I am a junkyard junkie, love going down there for little parts that I can get cheap and just like going. On my blazer the shield, compartment, whatever its name is, that covers the evaporator, has almost completely lost the top due to the thing just literally falling apart. Doing some junkyard research I have found out this. I found 3 96-98 blazers at the junkyards that appeared to have the same problem, the cover over the evaporator just eroding away and falls apart when you touch it. It also appears all three of them had the original Evaporator in them as I took two apart and one was just wide open where you could see the evap.

Now I found two others in the same years 1997 and 1998 where that compartment was strong as heck, not fragile at all. To be honest it looked like both of them had the compartment replaced as both no longer had the factory stickers on them as the others did about the refrigerant and such. Liked one so much I took both sides off, side for evap and side for fan and the junkyard charged me 10 bucks. Took them home and cleaned them up and they are like brand new. GM wants about $60 per side. Forgot, on both of these units where the cover was intact they had replacement evaporators in them. This led me to believe the evap go and after seeing 3 of them with these covers that break in your hands do to ?????, as mine is doing now on my own truck, thats why I am replacing the evap and fan. I know its a big job but I am not currently working and have a lot of time on my hands.

As a matter of fact, going down to Arizona Mobil Air on Tuesday to purchase everything. Does the freon leaking inside this case/cover for the fan and evap cause it to deteriorate after awhile ? I am very fortunate to have a neighbor is is an excellent mechanic and will make sure everything is installed right, check it and charge it up for me. He has all the professional tools such as to evacuate a system. Guy is wonderful and there is always people dropping cars off for him to repair. He is not a home garage type mechanic either, the guy is great, he is most definitely a fine tuned professional as I have lived here for 14 years and he has always worked on everything I own and has been wonderful. He has been helping me out with repairs since I have been out of work. He hates S10 chevy Blazers He is right, good truck but always little things going wrong.

Anyway, sorry to take up your time, just curious about the evap cover. Any suggestions on brand I should buy ? It appears they have a new one for my truck for under 300 , which I think is a good price. Should I leave the condenser if I flush it out ? Really may just do that as it appears not to be leaking at all. Thank You for your time and will find my way to Clarendon Ave. sometime Tues Morn.

Sorry this was so long

We get them in all the time, some crumble, I think from heat, others look like new, anyway, when at Arizona mobile air, ask them about the Sanden or Seltic clone replacement compressors, I have the seltic on mine for about two years now, (maybe three years?) not a single complaint..

Nothing wrong with S-10's; been very happy with all 4 I have owned.

Since you are changing a leaking compressor and not a internally failed one, you should be able to flush the condenser.

Put a new heater core in it while you have the dash tore apart.

Thanks for all the answers. Will save the heater core for another time as funds are at a minimum right now and second, do not take the dash apart on this model to get at the evaporator. Done completely from the engine compartment. I wll have to disconnect the on board computer and take off the inner passenger side fender.

I was thinking to take off the old case one side at a time then replace it the same way. I can put the blower side on, replace the inner fender and all the crap on top of it, then install the right or engine side of the case along with the evaporator.

If this is common, the case falling apart, then maybe my evap is good. I will take it apart and put what. 60lbs of pressure on it and see if it drops ? I can rig up a shrader valve type of deal with a pressure gauge and pressure it up with my compressor. Does that sound logical? I just figure replacing it as I was replacing the case anyway and I really hate doing things twice. Do you guys know if I can pay over the internet and just pick the parts up ?

send an e-mail to the guys at ackits,com and you can arrange paying on line I guess, but don't forget to ask about the Seltic replacement compressor, I feel it's much better than the GM compressor, but they do have both...
