did you try to adjust the dimer switch for dash lights?

Sounds like a open wire. You can always run one from the other side If you need further help, I’m available over the phone at https://www.6ya.com/expert/edward_020b3320326d263d

Check the battery voltage you need at least 12 volts.

Looks strange what you said. Since you pushed the cigarette lighter in,means that made a contact to receive power to heat the element. Since you asked for that and immediately you have lost Radio and Heater,means that either you had somewhere a bad contact and blown the fuse for radio and heater.Now having as you said fuses okay surely is strange. If you can,try to remove the the dash holding the cigarette lighter and see at the back where the wires are and see if you have any bad contact.or some radios have an extra glass fuse see if is any check if is blown. the same also for the heater. Always work with ignition OFF,to avoid any contact .

You never use a 160 statThat was a 1960's thing to do,when there were no computersI ran a 160 in my 1965 vette, just to see whatwould happen.I had no problems & built my own motorsYour best to go to a shop that has been around for yearsin the same place with the same ownerMay want to ask a local vette club for a place they useI don't know when,why ,etc your issues started or thevehicle history.Usually a head gasket,if you loosing coolantWater pump is eaten up insideSome engines use reverse flow for coolant,if you just had work done on itNeed to know that product to work on it.

Check whether the COIL WORKS, and also CHECK or replace the CAPACITOR next to the coil----it's cheap.

There should be a connector under the dash - you can use a scanner for OBD I or a jumper wire to make the check engine light flash.

My first guess would be the fuel pump. Alot of defective pumps will operate until they warm up.

clean throttle body with carb cleaner

check n make sure the converter isnt plugged

1st I'll need to know what the problem is with them exactly, won't flip up, headlight bulbs are not turning on but light carriages do flip into the up position?? What? What work have you done if any to try and repair whatever this problem is with the headlights? Throw me a bone here, I own a 1996 C4 now and have rebuilt another (84) from a rolling wreak. I know thwe problems wit the lights.
