I have a 93 s-10
Don't replace anything unless you need to. Disconnect the neg battery cable...
Find and Remove the IAC valve and the MAF sensor and clean both with MAF cleaner...pay particular attention to the IAC...spray it liberally and wipe it in a downward motion trying not to turn the pintle..remove as much carbon as you can.
Let the parts dry, then replace them. Reconnect the battery leads...start the vehicle without any accessories running...leave for 10 minutes...go for a drive for another 10-15 minutes so the idle can readjust...all done..cheers
Note, all this will only take about 15-20 minutes if you have the tools...you will need to remove torque screws, i think T15? ....and a wrench for the battery..and you will save about $300.. cheers
How to fix my 98 chevy blazer overheating
First, see if the radiator fans are running properly and the water pump belt is on correctly and there's no play in the water pump pulley. Check the front of the radiator fins for clogging. Then check the operation of the thermostat. If those check out, perform a cooling system pressure test on the system and the radiator cap.

Hello Dennis,
Is this only occurring at Idle? In other words, if at speed, you turn on fan ac controls and it runs fine (until you return to idle such as at a stop light)?
If so, then I would suspect the IAC (Idle Air Control) valve. When you turn on the fan control and the compressor kicks in, the IAC circuit is supposed to maintain the engine idle.
I recommend checking the IAC valve first, then let us know your findings.
Location of transmission interlock switch on 1996 dodge ram, 1500
This sounds like a transmission problem.
The interlock only prevents the shifter from moving, but has no impact on actual transmission operation. That is, the interlock has nothing to do with the trucks ability to coast backwards.
Our beloved Dodges are notorious for transmission failures. I recommend having it checked by a transmission professional.
1996 s10 blazer will stall out while actively
This may only be a suggestion, but I had a similar problem with my 89 s10 with a 4.3l Engine and a 20 gallon tank. After days of diagnoses, I found the fuel pump was going bad. Replaced the pump and bingo, problem solved. This may not be your problem, but it is a start. Might want to check fuel filter. I have seen that to be a problem with other vehicles, especially, 4 cylinder engine and not so much on a Chevy.
Good luck.
Problems with 93 chevy blazer
Your blazer has central fuel injection (CFI). You said you changed injectors, but your injector in inside the intake manifold, and only has one injector and a "spider" of nylon tubes from the central injector to each intake port. It is common for these spiders to break, causing fuel to leak into the inside of the manifold, and cause problems like you described. The spiders are available as reconditioned and are quite expensive,
1997 Chevrolet Cavalier Condensate Drain Issue
Does the fluid on floor resemble the radiator fluid? Quite possibly the age of the vehicle combined with not flushing the cooling system. Including the heater core. Has caused the heater core to leak inside the car. How full is the radiator? The part isn’t usually very much. However it can be a challenging DIY repair. A repair manual for said vehicle should have a trouble shooting section to help you diagnose & repair your vehicle
Why do my brake and tailights go out when i press on the brake
I seem to recall that usually was a grounding issue. If you look around the brake light housing you might see rust (on the inside where the screws are or where the housing touches the body. If you're up to it (difficulty depends on the car) you can take the screws and housing out and make sure you brush off any rust/corrosion. Some older cars might have a wire that grounds, you can check if you have one. Just take the screw or bolt out and wirebrush til you see clean metal. There are terminal (CRC makes some) cleaners you can use to augment the wire brush (or sandpaper). Also there are corrosion protection sprays (used for your battery, and the one I have sprays red) you must put it on afterwards as it's non-conductive. The bare metal will corrode again somewhat faster otherwise.
While not as likely, it's possible your main ground wire from the battery to the body is corroded, so something else to check.
Good luck, and let us know if this helps.
P.S. - Depending on where you live, corrosion might be normal (salt in winter or near the ocean), but if not, then check your trunk for leaks as well. If not that, it also could be an issue with the housing seal.

Did you check the main fuses? Sorry, I know how it is when the wife is not happy with her ride.
Hey, the cd player on
If it's what I think it is, the question is whether you have had kids in the car... (or annoying friends). I had the same issue with my radio and it turns out the cd player was being used as a coin collector.
I would disconnect the battery (following Chevrolet instructions so you don't hose the computer), then take the radio out and shake them loose (gently). (They never got the candy bar, but maybe you made some coin!)
Eventually it fried my radio, but I was able to get it repaired (it was new enough then to not just dump it). I had to be the "Fonz" and bang on the dash to get it to work sometimes.
