Question about Mazda B4000

2 Answers

A/C compressor won't engage.

Last week when I drove the truck ('97 Mazda B4000) the a/c worked great, Cold air, no noises. This week, the a/c compressor won't come on. I've looked in the manual for fuses and or cb's. It's just seems that it's not getting a signal to come on.

    No, retarded newbie. Knew that there was a series of relays/cbs/fuses in the food chain but don't know the nomeclature nor the location of said relay.


    Good internet name, meterologist?

    In my comment, I was refering to me as the retarded newbie, not you. My apologies is that wasn't clear.
    Thanks for the help.

    I'm trying different venues to correct a misperception that I may have created. When I referred to retarded newbie, I was referring to myself. I would never make that sort of remark, especially to someone trying to help.
    I apologize if I gave that impression.

My 94 B4000 has a fuse/relay box right behind the battery on Driver's side, under the hood. The clip to open it is right against the fender. With the cover open, it ought to tell you which relay is for A/C.
You won't find relays listed in your Part's house database, just go to fuses and you'll find one hanging on the wall.

1998 Mazda B4000 truck wont start sometimes

When you say it won't start, do you have any power at all, does the radio play? Does it click or make a noise of any kind? Is it a cold non start or a warmed up non start? There are a lot of factors to consider in a non start. I still have an occasional cold non start, with full power to my lights, radio, etc. Don't want to make myself sound dumb, but for me it was gear shift (controller). Not really the safety neutral switch, but put it in neutral or move the gear lever and my car would start right away. Chances are while waiting to let it start up you have hit the handle a few times and maybe knocked into position to let it start. If this isn't your problem more info is needed.

I have a Montero Sport 2003, last week I had Freon added to be prepared for the summer, I noticed a noise and ask the mechanic, he said it was the fan but nothing to worry about. I drove the Montero for 2...

If the noise started after you added the Freon, then it perhaps is your AC clutch. Normally if you have an automatic AC system, then when the Freon gets low, the auto system will not allow the AC to engage, only allowing the fan to circulate outside air. In order to add Freon to the system, the AC lock out has to be over ridden, in order for the compressor to **** in the Freon. This in turn engages the AC system so that the clutch engages, thus engages your AC system. The clutch bearings may be at fault.

I've got a '97 Mazda B2300 P/U, while the blower and A/C compressor work, the air in the cabin is neither heated nor cooled. Any thoughts on what the problem might be?

grip the low pressure line when the a/c is on, if it isnt cold, the a/c isnt cooling. the low pressure line goes from the firewall to the compressor.

1994 Mazda B4000 4WD V6. Check engine light on. Truck

if i remember right if the battery light and check engine light is on, your alternators may be bad. your battery may just have enough to keep it running for a minute or so. you can take it out and get it tested at a auto parts store. or try charging your battery for awhile and see if it stays on longer. if this is completely wrong let me know

I think the air compressor is bad in the truck

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.
