I put in a v8 into a v6 car and had takin the computer out. What wire gets me heat back/ blower and where do you hook it up at??? Thanks!!!

 

It would be helpful to know what year and make the car is...

 

If you are talking about a G-body, the computer has nothing to do with the HVAC system. How about some photos of the HVAC box area so we can see what you're talking about?

 

The G-body computer does enable or disable the compressor clutch with a relay, but does nothing to the blower.

 

Good clarification. That's what I meant to say...

 

I'm still waiting to find out what he's actually talking about.

I'm feeling done with "Twenty Questions" this month. Lay your question out in plain English and I'll help if I can.
I am not pulling it out of you like a dentist.

Sorry for the delay its a four dr 1983 olds cutlass supreme. Ever since I pulled off the computer the blowerdoesnt work

 

OK, look. There are a bunch of people here who want to help you, but you need to provide a LOT more information than that. The mind reading REALLY isn't working.

All we know is that you swapped the motor and ditched the computer. Do you actually have the HVAC wires connected to the relay? Is the ground wire for the motor in place? Did you reconnect the four-terminal connector near the distributor that provides power to the blower motor?

See? Without this information, we can't really help. Again, photos of the area would also help us see what's been done. All we know right now is that the car isn't stock. That's not particularly helpful.

 

Ill take some pictures today and post. The car is fully running everything for the distributor is hooked up. Ill post pictures shortly Thanks sorry about the low information

Is the problem both no heat and no blower, or do you have heat, just no blower? If you have no heat there is more than just an electrical hook up problem.

 

Before I pulled the V6 I had heat and blower. After this motor was put in and I detached what you see in the pictures I dont have a blower now at all. You switch the switch inside and nothing happens

 

I had a hunch.

The red wire in this connector is where the blower motor gets it's power. You need to reconnect it to the mating connector in the engine harness.

By the way, the two round two-wire connectors are for A/C sensors so they are not needed for heat only.

 

That might have been a clue that something wasn't reconnected.

 

By the way, the other thing I see in this picture is that the vacuum lines don't appear to be connected. That means that the flapper doors inside the car won't properly divert the air to the vents you select. The default position with no vacuum is simultaneous floor heat and defrost.

 

Thank you, Joe.
I have no G-body experience, so all I could have said was "plug all that stuff back in."

I will only add that I am impressed by the "efficiency" with which the accumulator was removed.

I realized something wasnt reconnected but theres no harness to hook it to Im pretty sure I unhooked it from the computers harness. And do the vaccum lines go to anything that supports vaccum? Carb or.intake? If there isnt a mating harness what do you do

 

Again, you did NOT unhook it from the computer harness. That connector joins the HVAC harness to the engine harness and provides power to the blower motor. It has nothing to do with the computer harness. The computer harness is a standalone harness that feeds through the firewall below the HVAC box. The engine harness comes from the firewall connector under the brake booster and runs across the back of the engine. There is a female four-terminal connector that this plugs into.

One of the vacuum hoses goes to the vacuum ball, which has a check valve. The vacuum ball is fed from straight manifold vacuum. The other hose goes to the heater control valve. If you've deleted the heater control valve, then plug that hose. You still need vacuum to operate the flapper doors, and you need the vacuum ball and check valve to ensure that the doors stay in position even at low engine vacuum.

Sorry, but the lesson here MIGHT be to label stuff before randomly disconnecting it, or better get, get a Chassis Service Manual first.

 

Joe... Thanks for your help a labeled most everything I knew I had to besides that I thought I was going to go without and for some reason I thought it came off my computer but I went out and seen the plug laying there right away after you said where it was at. Im a first timer at this so it has been one long learning experience for me. Im still a young buck. I do appreicate your help. Those vaccums were never hooked up ever since I have owned the car which explains why I was never able to switch vents heat has never blown from the center dash only defrost and the floor. I do have heat now thanks Joe.

 

Hope you still have all the stuff you removed so you can find the blower harness!
A big rule of mine is never toss away anything until I know a job is done right. I have saved myself several times in following that.

 

I doubt he'll be able to reconnect that evaporator, though.

- Eric

 

I havent cut any wires just laid them to the side until everything works again then the unused ones can disappear. The evaporator ummm no lol its toast but I wont be using ac i havent ever had it i have four windows

 

My blower works again I found the other side

 

Nuthin' that can't be fixed with a TIG.

 

Now Joe, don't go getting me excited.

- Eric

 

Still not a reason to chunk it, providing it was being replaced.
Mine was junk but kept it around. After the new one I got from Oreilys did not fit right, I compared it to the old one. The new one was 1/2" thicker! So back it the store it went.

My front wheel bearing thrust washers were stuck to my old wheel bearings which were in the trash pile. Did not know about them til reassy 5 months later - glad I still had em!

 

"I am impressed by the "efficiency" with which the accumulator was removed."

:-)

 

I think this has became a diss on me thread.....

 

Aw, c'mon.

When you post up a problem, and the answer, after 18 posts, is, "Plug it in," you've got to expect a little ribbing.

And my comment about your evaporator line wasn't about you, it was about your car (unless of course you're the one who hacksawed it off, in which case, yes, it was about you).

Cheer up!

- Eric

 

I hadnt realized it just plugged in I thought you had to wire it so that was my bad. Hacking it off yes all me but it also has a all new system going in it but i dought i put it in because i dont ever use ac the other didnt work at all but i have kept all the old stuff in case lol nothing wrong with hacking it off I didnt wanna take it apart and pull em out
