Not for sure if this is the right place for this topic? But

Just picked up my project mazda a 89 b2200 extended cab with 116,xxx Well I got a couple problems since im new to this I would like some help where to begin first the Gas Gauge and Temp Gauge dont work and last the heater wont work so if you all can point me in the right direction on thes problems i would appreciate it thank you

The gauges are probably the sending units gone bad.

it may not be the sending units. my fuel gauge and temp gauge went out too and i changed the sending units and still got nothing, so then i changed out the gauges and they worked for about 15 minutes and they went out again. i think i might have a short somewhere. haven't figured it out yet. somthin to think about before you start spending big bucks.

so how much is a sending unit anyways

the temp sending unit is cheap but the fuel sending unit if i remember right was like 200 or 250 from mazda. i will try to find the receipt and let you know.

fuel sending unit for an 89 b220 e-cab is $51 from Autozone, i just looked it up on their site

You the MAN

man that sucks. those @$$holes told me i had to go to the factory. damnit!

NEVER go to the factory for squat!

Re heater not working is fan not blowing hot air or is there no hot air coming from heater? Fan is fused check it first. Any evidence of coolant leakinside cab? Heater core may be bad, pretty easy to find in junk yards. If temp gauge isnt working I guess you dont know if truck is reaching operating temp or not but may need new thermostat and coolant change. Hope this helps. BJ
