my 1992 eldorado while driving at night sometimes my lights go out sometimes for 10 seconds or as long as a minute,and my climate controll just shows all lines it seem that if i stop and shut the iginition of for a bit when i restart it seems fine,somedays it may not happen but other days it seem quite frequent,where should i look first for the prob,any help would be appreciated

 

There should be codes stored in some module in car, check and post.

 

the codes ,will they be listed as history or current,i have no current codes but i think there are several in history,is that the ones you want??

 

the codes in history are io33,io34,io37 and ro33 ro34 and ro61

 

i guess no one can help with my headlight issue ??

 

Codes 33&34 are MAP Sensor Circuit Faults, 37 is a TCC Brake Switch Circuit Fault, and 61 is an A/C Preformance code.

The headlights could be a grounding issue somewhere in the circuit, but I've seen similar problems being related to the Body Control Modual (BCM).

 

The I codes are data line faults, and that is why ECC panel reads dashes when it happens. R codes are air bag system faults. Checking grounds are where you start, what kind of mods does car have or is it pure stock. Do you have manual?
