1983 Chevrolet El Camino maintenance manual heater blower proble

It can only be a faulty switch. See the two spade connectors here? Remove your connector and put two wires direct to the battery. If it stops and starts as normal when you make and break the connection, it proves it is the switch that is faulty.

the oil dipstick is located just below spark plug 6

I just had a question like this the other day, also on an El Camino.
We talked about the high blower relay being the possible cause.

this is not an easy fix i can help but i need to know how much auto repair do you know because you might have to do a transmission filter and fluid change let me know

Please tell me what the probles are you have?? Fuel pressure from the pump should be 5-7 PSI

I beleive that would be the resistor pack that would need replacing.

It is usually near the fan.

check the wires for loose connection and the fuse or fusible link.

Yes. GM made all Chevrolet El Camino's and GMC Caballero's excactly the same, save for badge and trim packages. You can interchange parts with El Camino/Malibu/Monte Carlo cars and some S-10 trim peices will fit. But all three Cars will interchange interior parts. as for the bumpers, Only El camino/Malibu/Caballero will fit without modifying them. A simple Bolt-On and go.
