Dash lights om 1987 mercedes 190e out at heater controls

see if this link helps.
Turn signals not working in my 1984 mercedes benz 190E Google Search

2 forward brackets unclip and fold away and then door pivots up to show fuses. The screwed doen cover has 4 screws to come off uncovering the relays behind the fuses.

The stop leak has most likely clogged the heater core. Or the blend door for the HVAC isnt working in the dash anymore. Either way a big job to fix them.

does this help at all?

There are 2 PDF documents to open - above the photo on the site.

The first - the Routing Guide - shows the reference for the belt diagram (1987 MERC 190E) which is 6-2 on page 92 of the Guide.
The second PDF shows the belt diagram for 6-2.

Hope this helps.

cold start relay either the fuse in the relay, or the relay itself.

There could be 4, 5, or 6 pulleys on the 190E 2.6. Here they are.

hello,be sure your starter motor is working,fly wheel gear(for starter bendix drive)should also check,valve clearance also,try to rotate your engine with socket 27mm,(manually) maybe your piston is stuck-up,ty

hi,you have to remove your under dash,drill the lock on steering lock mechanism,you can turn the key,renew steering lock mechanism and tumbler,ty

Seems there may be a issue with the combination switch
