I have 2002 Chevy s10 with ac issues. All blend doors and actuators work properly. Clutch engages on compressor. Blows warm air when ac is on. When I put a guage on it the psI stays on max and doesn't change. Could my compressor be bad and the clutch still engage? I've never seen a compressor clutch engage and compressor bad, is it possible. I think I've eliminated all else

all cars with Hvac, same answer an newer more.
V6 engine?
all fuses good
the blend door motor or controls are bad./
but wait car is 21years old wana bet 2 or 3 things wrong.
what year did heat or AC cold ever work rigth.
what I do is on blow high.
I fix heat first. as that can fix AC next. see and is far less work.
1: fuses good. all.
2: make sure engine coolant hits 180f first or more if not the thermostat is NO GOOD ,7 year live and is 3x that now,???
3: all that good I put my hands then on the 2 heater core hose and both are to hot to hold there hand flies off. or TODAY for 10 years now mY IR gun $15 shows 180f on both hoses for sure hot and same. if not core needs to be flushed, I use hose garden there,.
4: ok dampers are bad.

easy no?, get heat first.
the damper may becalled the blend door, and can stick in any wrong position, even half cold and hot, so both fail.
ac on , ac compressor spins due to clutch there engaged.

let me now see your dampers, I bet are not cable drive. (NOT )
but motors. yes! (Drive + gears)
$15 motor, +door
the cheezy door is plastic, and its axle too and they can break.
no fun ever that last one.
5 doors in this beast, recirc door must close for sure AC cold wanted.
check out this drawing,.
A AND B MUST WORK RIGHT FIRST.
for sure B is bad, IMO.

good luck , but do the tests to find cause
my jeep i pull he damper b and the axle see there is not broken
then i spin that by hand and can go full range
the motor is dead. easy easy fix, 2/3 screens and a whopping $15

undercharged--overcharged--compressor failure--blown fuse/relay--mode door vent--climate control failure--

Can you tell if compressor clutch is engaged? If clutch isn't engaged only the belt pulley will be moving and the compressor clutch is not engaged. If not engaged, no ac.

Can you check for applicable hvac codes? To check codes, your-self, at the least, you need an obd2 code reader, that will check manufacturer specific codes as well as po.

I haven't looked at your wiring, you could probably check voltage and ground for compressor, hvac on.
In the diagram, you see applicable fuses--clutch relay-- the top wire at ac clutch is voltage--black wire is ground.

There could be several problems. If the a/c is properly filled with oil and refrigerant, and the compressor is working, the line from the compressor to the condenser should be hot. the line from the condenser should be uncomfortably warm. The line from the evaporator should be quite cold. If all this is so, the air inside should be cold. If not the actuator in the dash that operates the blend door may be broken or the blend door is stuck in the hot position. I hope this helps:)

Could be, check the door and see if it works correctly

Possible blend air door malfunction.

Make sure your blend door is closing all the way and that the actuator actually works.

It can be issue with blend door actuator or vacuum leak or loose vacuum hose connection.

Thanks.

If it is cold in the rear, that eliminates the "freon" part of the system. (It apparently has enough freon and the compressor is apparently working.)

So that leaves you with a blend-air door problem on the front A/C unit. That may be a blend-air door actuator, a broken blend-air door, or a faulty control head. (Proper diagnosis required)

i had same problem 2 years ago. the actuator door tube was snapped in half and i used acquarium tubing to splice together. The tube runs along the passenger front well well inside engine and meets under the battery carriage. I could not tell anything was wrong without removing the battery to get a closer look. works like a champ now.

Also: there is also an inline venturi filter that fits in the aluminum tubing on the compressor, it may be clogged. You will have to have the freon sucked out to replace the filter. Check back with me so I can help more if this doesnt solve your problem.
