Thanks for responding.
It’s a 2001 gmc sonoma with a 4.3. It’s rear wheel drive.
It has 170,000 miles on it.
I do have AC, but when ever I turn it on my engine bogs down to the point where getting on a busy freeway feels sketchy. It’s very slow. It does it no matter if it’s hot or cold out.
My truck runs perfect all the time when the AC is off. I live in Northern California where it can get up in the 110s and have never had a problem overheating.
I’m wondering if the fan noise/ decrease in power is normal. I find it hard to believe it is. I don’t think the truck would sell.
I bought it used. If it had an fan clutch without ac installed from the previous owner could the extra stress cause the fan to constantly blow like it does?
Do you think the fan constantly roaring , along with the decreased power, could be normal.
I replaced my aic valve and have noticed my truck has been idling high sometimes. Could that be related.
Thanks for any input. I’m new to working on cars and know very little about how the ac works.
Thanks for feedback
