I'm having an issue with my '93 fleetwood Brougham's Air Conditioning and hope you guys here can help me out. so here goes my air conditioning is acting weird it blows cold BUT it only blow like its on medium even if I put it on the maximum "Hi Fan" setting and its even worse when I put it on the medium or low settings.

Like I said its still really cold but its not blowing as hard as it was a couple of days ago. My A/C unit by unit I mean the compressor,evac dryer,orris tubes and lines were all replaced about a year ago with new AC Delco parts and its been fine all this time it just started this the other day,so what gives? Could this be a blower motor issue perhaps? I don't Think its a leak because its still cold I'm really stumped here guys thanks for any help.

sounds like a possible blower motor resistor
I have one here if it turns out to be that
its located under the panel on the pass side dash,
sometimes the terminals get green and corroded
and the fan doesnt get up to speed
I also have a couple blower motors here

Hi fleetwood guy whats a blower motor resister is both that and the blower motor located under the dash panel on the passenger side? Is this panel the cover right under the glove box? Are either of these hard to change out or get to? Should I try cleaning the blower motor resistor's connectors maybe? last thing is are these parts expensive? thanks for your help so far. Also forgot to mention it also does the same thing when the defrosters are on as well.

yes on location, pass side under dash g/box, both pretty easy to deal with
if this is just a fan speed issue then i would suspect resistor first then blower 2nd, try running the fan on high , while you push on the plugs on the resistor
if the speed of the fan picks up then its the connection
I posted a pic of the ac/ box on the board Ill try to reup it
those parts used are reasonable

2-- 7mm screws hold it in place (resistor)
try unplugging the plugs and look for the green corrosion

the 1243 are from another post, disregard them, I have it circled here
