Re: [DML] Poor airflow thru heater-A/C

[Jake Kamphoefner <jakekamp@xxxxxxxxxxxxx>]

Dave,
 
I was recently in the same situation.  Here's a couple things I checked to fix my problem:
 
- Make sure the blower and squirrel cage are correct.  There are a lot of GM equivalents that fit perfectly, but the blower motor either turns the wrong direction, or the squirrel cage is cut to the mirror of the DeLorean (that is, it is made so that turning the opposite direction causes the air to flow the same direction).  After I replaced my blower with an OEM that I bought amongst a hand-full of other parts, my air flow highly increased.
 
- I also resealed the infamous foam on the back of the A/C box
 
- Cleaning the evap?  Here's how I did it.  I taped a wet shop vac on to the drain hose.  Then I removed the blower motor and the resistor to give extra room to get my hands in, and pulled back my carpet to lay down some old towels.  Start by dumping a little water into the evaporator box, then use your contortionist skills to reach into the box and pull that gunk out.  Keep pouring water through it and make sure it's making it to the vac.  You may have to stop to unclog the line a couple times.  Then I put a length of clear hose on the end of my garden hose, and fed it into the box.  With the hose on *slow* (it's a lot more water when coming out of the small clear hose), I nozzled the tube with my thumb and sprayed the evaporator for a long time.  Be careful not to get more water in than the drain hose can handle.
 
Oh yeah, and this job sucks.  But it's better than removing the evap.

I'm having an issue with the Air conditioner/Heater where not much air

other D, the airflow on "4" is about like "2" but it's definitly 
running the fan on high. 

I've verified that
