1983-1994 Chevrolet Blazer: How come it won't start after it sits for awhile

Sun, 19 Oct 2025 19:22:08 -0700

97 blazer just bought had 4 days runs great no ticks knocks squeals. But after it sits over night or the 8 hours i work it has to be primed before it will start. I thought it was out of gas the first day cause I was told gauge wasn't correct. Only took $10 to fill it up that wasn't the problem the other. 2 other times started after just a couple primes. Last night tried starting it for almost 2 hours till the battery died and nothing went to pick it up this morning from work put cables on it because the battery was dead I primed it twice and it started right up no problem

1995-2005 Blazer: Why won't my AC send signal to the AC Compressor?

Sat, 02 Sep 2023 00:15:32 -0700

EDIT3: Since I replaced the switch, I’m led to believe that the only other things it could be are either the AC accumulator or the HVAC actuator. The actuator failing is a common issue with this type of car according to online resources, however, that is the more expensive of the two options. I may have to replace the accumulator to see if that works since it only costs $30. If there are any more suggestions or ways to properly diagnose, I’ll gladly try.

EDIT2: I replaced the low pressure switch and it still hasn’t fixed the issue.

EDIT: I just found a video where someone also bypasses the relay. This is exactly what I did, and this gentlemen seems to be having the same exact issue.

SUMMARY:

Hello. So I went to recharge the AC in my vehicle and noticed that the AC clutch wasn’t spinning at all. I did some troubleshooting, and I now think it has something to do with the computer in my car.

I checked every fuse in the car. Replaced one for my cigarette lighter, and all the rest are fine.

In the engine fuse box, there’s a AC fuse and a relay. The fuse is good, and I used a multi-meter and a 12v battery to test the relay, but just in case, I also swapped relays with the horn to make sure they both work. (They do).

Lastly I used a paperclip to bypass the relay on the fuse box, and the clutch started, which leads me to believe that the relay is not being triggered when I tell the car to turn on the AC.

The AC Compressor/Clutch
The Fuses
The Fusebox

I’m not sure what else is left to try, but it’s going to start getting hot soon, and I’d really like to have my AC working.
