Question about 1998 Volvo S70
I can't figure out if it's the fuse or a belt. The HVAC is not blowing out any air what so ever. The seat warmers work and the back window defrost works fine. Any suggestions before I get bent over by some mechanic??? Thank you - Single mom with little cash....
First check your fuses and clean them and coat them with Dielectric grease, then try replacing the Relay if that does not fix it.

if the fan is blowing this could be a problem with the climate controll switch that changes the direction of air from floor to defrost to vents, some are vacuum controlled through a vacuum operated mechanism that opens and closes a door in the vents which redirects the air to different places.

I have the same car and had the same problem. The inside air intake for the heater system is located above the passenger's feet. An empty plastic bag got sucked in there and kept the door from moving properly. I had to take off a few panels, then one on the vent. Once I removed the bag, no problem.

If you touched any of the A/C controls within 45 seconds of starting your Suburban (after the battery change), you messed up the 'calibration mode' of the HVAC.
Pull the HVAC fuse (10amp) under the hood, and pull the two adjacent fuses (30 and 10amp) under the dash listed as 'climate control' in the manual.
Push the fuses back in, restart your car, but DONT TOUCH ANY of the A/C controls for 90 seconds.
I bet the A/C starts working again normally.
