What's the trick to install the HVAC box???

Alright, so pulled everything out nicely to replace the resistor pack. Got it all wired back together, and now trying to reinstall the HVAC box...and after an HOUR of trying to push it into place...stupid thing won't "slip" for me.

I placed the blower in first, into it's corner, then I angled the HVAC box so that the blower side goes in first. Then level the box out somewhat, and I can get it so that there is just the corner sticking up on the heater core side of the HVAC box, but I can't get it to go any further. On the blower side, the top of the box is hitting the Master brake Booster, so there is no more give there. The passenger side seems to be hung up on something...but there is nothing for it to be hung up on.

Am I supposed to install the blower and the HVAC as one unit? Was I supposed to put the HVAC side in on it's "side" and then twist it into place...what is the trick. Help me out guys...its the only thing I have left to do in the front.

Thanks.

they won't go in as one, too big

I actually strung a piece of wire on the blower so that I could tug on it and it rotates the blower CCW a little so that the two would mate more easily. Without it it is kind of jiggle jiggle push push swear jiggle to get the heater box to drop into the groove in the blower

Also the passenger side end fits below the frame rail into the void so it must be low enough to do that

I took pictures notice in pic 5 the yellow wire looped through a crimp terminal to tug on, it is attached to the bottom of the blower

I also clipped a tiny bit off of the top of the air distribution box inlet as it threatened to get damaged when putting the heater box in and out

As I recall you actually have to pic the airbox up by the hose outlet to get it to slide towards the passenger side

Yeah agreed you can't put them in as one unit, gotta put in one and then the other and they will be like this '^' and then you press at the top, to push them down. Pretty sure that is how I did mine.

I put the fan in place turned up just a little. Then you need to find the spot where the HVAC box sits as far towards the passenger side as possible. I think it's slightly elevated of the bottom then slide it down and in. It is a super pain in the ass as it only fits in one specific way, but you don't need to force it or anything or do any tricks with the fan. It drops right in when you have it right.

Thanks Guys...I think you have solved my case. I didn't try tucking the heater core side in first. When I pulled mine out, I had pulled the heater core up first (I think)...but reversing the process and bringing them down to an nice angle makes a lot of sense. Thanks for the VERY accurate pics Exigegus, it helps A LOT!!!

That will be tackled/done tonight I hope, and then the process of putting the rest of the front end together.

I put the wire pull on when I was doing my AC rework thread [ https://www.lotustalk.com/forums/f313...ework-348738/d ] and I was going to lose my mind taking the heater out and in 20 times. The blower needs to be tipped back to get the heater assembly in but then needs to tip back forward to line up with the heater assembly, and you cannot get a grip on it.
