No Speedo

[weekendracer728]

I have a '89 chev k1500 4x4 that the speedo has not worked since I bought a couple of months ago. I didnt really care, just used the gps, but know would like to have it. The brake warning light is on and check engine light. Check engine light is for the speedo.

One day I was driving home and my door jamb switch broke so the dome lights stayed on. Pulled the fuse for them and brake warning light went out. The speedo started to work a little while later and it seemed to shift better. Fix the door switch and it quit working.

I have checked over every wire and found nothing. The vss is good and the shift relay is good. I think it has to do with that brake warning light. Cause I have no speedo, no cruise, and the tranny seems to shift different.
