Hello,

well I have a 1995 E420, the problem is the AC.

when I turn on the AC the air comes out cold, you can hear the
compressor working, the blower only seems to work at really low speeds.
so hardly any air comes out. It comes out really cold. But the air comes out
really little. Any Suggestions. Thank you guys

Like most things on these cars, the culprit can be one of a few things ... I would say to test the push button unit (PBU) voltage readings by the brake booster on the firewall (under VIN number plate and water drainage on driver's side I guess you could say) ... with key turned to on and defroster setting, red wire to black wire should be about 12 volts, yellow to black should change from 4.5 volts to 10 volts depending on high low setting on PBU ... different readings from this and PBU might be culprit ... the other possibility is the blower motor regulator is shot .... that is located under the blower motor ... you could find a DIY on this site as it is located way under the wiper in the engine bay .... to test that, apply 12 volts directly to the blower motor and if you hear its loud as hell, then the regulator will need to be replaced .... this should help too http://www.peachparts.com/shopforum/showthread.php?t=251372&highlight=test+push+button

Thanks I will keep reading on, I'll take your advice, and start checking the regulator. Thanks

While your at it- replace the cabin airfilters.

Daughter had the same problem. I would kick the inside right of the driver's well near the gas pedal and it would kick on and blow hard. Then it finally stopped blowing. Ordered a new blower motor with squirell cages and solved the problem. About a $100 bucks and used the DIY link to do it. Was easy. Blows like a banshee now.

Thanks guys for all your input, I will be fixing it soon and posting results and pictures.
Thanks

Rugulator under the blower controls power to the blower. If its always at low sppeed thats most likely the issue. That or worn blower brushes or bearings need grease.
