I have found my a/c filter to be wet on the bottom edge when I take it out to change the filter.?

Most likely the evaporator drain is clogged.It is not serious,but you will need to take care of it before it starts leaking into the passenger compartment.

omg! your truck would not have a pump, that's a suction, and except you p.c. 5000 to 35000 psi of diesel gasoline hitting you in the face, do no longer even mess along with your injectors. Did you pump up the primer bulb on the precise of the filter out assembly? you need to shop at it until eventually it gets stressful. If it in no way gets stressful, then you definately've slightly an infection in the primer that's combating it from working wisely, and it would be needed to take it to an authorized GM Durmax tech. as quickly as back, i won't stress adequate that no count what those each physique is telling you, do no longer...do no longer...do no longer touch those injectors or gasoline lines, or you would be sorry. there's a primer bulb.

i would'nt know...hold on.

was it damp or soaking wet.

if it was just lil bit bit i think it might be moisture.

if its soaking then it's somehing else.

i think theres supposed to be a weatherguard ot a gasket of type around it. check for those.

I agree with Auto A/C Guy.
