Heater access Cut Out for cleaning/ servicing

[JAG1]

My heater blower on the 2001 got cleaned and lubed tonight and blows much better also no longer has the funny vibration sound.

 

However, not blowing as well as my 2002 with half the miles, I'm wondering if there is a strategic spot to cut out the plenum housing for access for cleaning. I'm not well versed on parts but I believe to be able to clean the evaporative cooler? is that right? Would be great.  funny... I always thought that was near the radiator

 

The blower was a quarter full of pine needles as was the cowel under the windshield so I know there is more yet to clean. I want cut out for future access

Best to remove the entire HVAC box and power wash the evaporator. Attempting to clean the evaporator in the cab is weak at best. Ive done a few cleaning through the dan hole but you really cant do it very well in the HVAC case.

actually I was wanting to save that for you Mike. Pay for it you know...... but for now I just need to get some cooling going as it's the worse part of summer right now. What is and where is the 'dan hole? I'm ready to back blow the whole system thru a vent with my back pack blower as it's so hot with a black truck.

Basically pull the blower motor. Then cover the floor with plastic. Then using a garden hose with good pressure keep working till the water run clear. What happens is the evaporator sweats, then dust is turned to mud. Then it dries into a dirt clod. You only be able to work on one side and only the center of the evaporator.
