Can u do a video showing how to check the other stuff that could make the compressor not kick on specifically on blazer

[@RBTheMechanic]

I don’t get lot of those but check to see pressure most important is pressure other wise ac will not kick on check fuse relay and if u got 2 wire ac pressure switch u can jump the wires to see if ac compressor clicks

[@qchenier]

Solucion, 1. Reley de 40 Amper, intervenir el cable positivo que conecta al compresor y utilizarlo como señal para el Reley, y Reley tomar una alimentación directa de Batería o Utilizar el cable naranja que alimenta el ping 87 del Relay que alimenta el soplador

Idk spanish

Check your resistor also,my issue isn't compressor but blower fan not working

[@RBTheMechanic]

Yes that could be resistor fuse relay or blower it self so check fuse resistor relay for blower motor also put blower motor speed on high to check if it works that by passing resistor and banging on blower motor can kick the blow on some times motor is the issue

[@vegasraiderspetef9883]

In my case even thou the screws are a major hassle to get out replacing the resistor fixed the problem

[@vegasraiderspetef9883]

@@RBTheMechanic hey it worked perfect for 3 days then then stopped working. Dorman is the brand of resistor ,I looked under the glove box all connections look good. Could it be the resistor failed or a bad relay that in the engine fuse box? I don't think it's the blower fan but B4 it

[@vegasraiderspetef9883]

Found a 15 Amp fuse under the hood next to a relay fuse. Replacing that did it

[@PerrysGaming]

What is the HVAC fused used for on the blazers? I have a 2002 and everytime I cut my AC on the HVAC fuse blows instantly. My AC fuse is fine however

[@RBTheMechanic]

Sorry I don’t have video on that but if fuse blow u need to find the shirt on circuit

[@jamesrobert782]

On mine the diode shorted out and burned, it was on the green and black wire that goes to the high pressure switch on the back of the compressor, i didnt replace it though, can i run the ac without that diode? Now the ac compressor clutch only kicks in first start in morning, then it gie soff and dont comeo on again? What could be the issue.

[@RBTheMechanic]

U need the diod it has function

[@RockymountainRobert]

​@RBTheMechanic , I Juat got a new diode, I'm going to put in on the wires it goes on, hopefully my ac stays working. Thanks.

My 1996 Sonoma 4.3 has a problem bro, i changed the AC Resister and it fixed the problem with not letting me use 1,2 AC Blow switch now All the switches work exept HIGH number 4 What could be the problem?

[@No.No.7]

And after A while the High number 4 Switch it kicks in and turns on, shuts off then stays on but i want it on All the time

[@RBTheMechanic]

High is direct either ur resistor is bad or switch

[@No.No.7]

@@RBTheMechanic so i can change the whole ac thing that’s with the Hi &Low ac?

[@RBTheMechanic]

@@No.No.7 u can try that

[@lanewright1143]

​@@No.No.7 did you get this figured out? Apologies just wondering.

[@jacobpenkava2980]

You have your high ans low ports mixed up ....

[@RBTheMechanic]

Thanks
