1995, Mazda B2300 standar
The heater stopped working (intermittently I do get some heat) on my 1995 B2300 (without a/c). It has a slider control for heat which seems to work fine I can feel it actuate the blend door through the glove box. I understand it is likely to be the heater control valve failing but I can't find it. Would appreciate any pointers on how to locate and replace it. Thanks

Welcome to the forum! Not a good time of year to be in Canada without a heater!
My Haynes repair manual for 93-97 Rangers has no mention of a heater control valve.
Here’s a shot of what it has about heater control. Maybe take a look at the vacuum line and motor coming in at the lower right in pic?

Also, here’s a thread that does mention valve, on a 97, same generation as your 95...

Thanks for your help, yes it is cold here without the heater working. It blows cold air 99% of the time since last week. I looked at the vacuum hose under the dash and all seems good but will look closer tomorrow.
The heater control valves they sell all have 4 hose connections and I only have 2 hoses to the heater core - perhaps there isn't one if there is no AC?

Could it be the heater control module?
