just wondering where to find condensate drains on 88 suburban air is blowing nice and cold just wondering where the condensate drains are was setting stoped for a while and never seen any water driping under the rear or front of the turck and am thinking the drains are clogged and dont wont be going down the road and some on in the back get socked with water becoues the rear unit isnt draining or carpets to get wet and mold and all that stuff
If OEM rear air, then drain is rubber slot next to aluminum manifold where a/c pipes go through the floor under rear of truck, Front drain is in behind A/D right below it...
Water dripping won't really happen unless you have high humidity-- say 50% or more.....if a/c pipe at A/D is sweating, then I'd expect drains to drip-- otherwise there is not enough humidity to create drippage.....
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
