Question about Mazda B4000
When i am driving alond and either turn on the AC or the Defrost, the truck makes a strange noise and keeps doing it till i turn the AC/Defrost off. If i am accelorating when i turn them on the truck lags big time, i'd say at least half the power is gone.
If your refrigerant level is OK and the truck blows cold air your compressor should be fine, in which case the noise is probably coming from the AC clutch which isn't too expensive or difficult to replace. If it doesn't blow cold air, switch the AC on and watch the compressor. If the clutch engages, but the compressor doesn't turn, the drive belt will squeal loudly and probably start to smoke. In that case it is the compressor which is expensive to replace. Most vehicles have an AC bypass that will temporarily cut out the compressor clutch under heavy load. If you are going uphill with the AC on or accelerating heavily you might notice warm air coming out of the vents for a short period until you let off the gas.
